Labs
0.  Lab Intro

Introduction to the optics lab.  Description of optical components we will be using throughout the semester, gaining hands-on familiarity with optics, light sources, detectors, power supplies, etc.  Familiarity with safety equipment.  Each team will get their own breadboard for the semester.  Overview of laboratory protocol, including lab-notebooks, and note-taking.

Discussion of "Plastic Fantastic".

No Manual
No Lab Report.
1.  Build Your Own Spectrometer(2 weeks) Students will begin this lab by studying simple diffraction gratings and optical components.  As they become acquainted with the equipment, they will begin to construct a home-made spectrometer.  They will learn about basic optical concepts (diffraction, reflection, spatial filtering, wavelength, the visible spectrum).  The final spectrometer could be used to measure emission from LEDs or lasers.   Accompanying lectures will focus on the wave nature of light and basic interaction of light with bulk media and wavelength-scale geometries.

Labview Program for Spectrometer Data Collection

Lab Report:  For this lab, your group will turn a 2-3 page brochure for the spectrometer you have built in class.  The brochure should descripe the operation of the system, it's specs, and should give examples of operation.  Include pricing information, as well as possible accessories for purchase!

See this example:  Horiba-JY i320

2. Holography (2 weeks)

Students will gain familiarity with the wave nature of light and working with lenses, mirrors, beamsplitters, and other basical optical components.  Students will build a Michelson Interferometer, which they will then modify to act as a holography set-up.  Students will expose holograms of 3D objects of their choosing, and then develop the holograms, and project them in the lab set-up.   Accompanying lectures will focus on the wave nature of light. 

Holography Lab Manual Link

Lab Report:  For this lab, you will turn in your Lab notebook.  Grading will be determined by the level of detail, legibility, and one simple question:  could someone recreate your results using only your lab notebook?

3. Nanotechnology (2 weeks) In this lab students will build an absorption/photoluminescence spectroscopy system. A PL/absorption system, using a hand-held fiber spectrometer, will be constructed using cage-rail optics, a white light source, a UV light-emitting-diode, and a handheld minispectrometer.  Students will characterize in-solution colloidal quantum dots of varying sizes, among other materials.   Accompanying lectures will focus on basic quantum mechanics, and nanotechnology in health and medicine, and energy applications.  Nanotechnology Lab Manual Link

Lab Report:  For this lab, you will prepare, as a group, a 3 page paper in the format of Applied Physics Letters describing the experiment undertaken, with figures, tables, data, etc. in order to present your results.

4. Solid State Lighting (1 week) In this lab, students will study three different forms of lighting: Incandescent, Compact Fluorescent, and Solid State (or LED).  Students will determine electrical power requirements for each type of lighting system, as well as the optical power output of each light bulb.  Students will also look at the spectral output of each light source, as well as characterize each light source using a thermal imaging camera.  Accompanying lectures will discuss optoelectronic devices such as LEDs, lasers, and detectors, as well as concepts related to energy usage and conservation, and will encourage students to think broadly about global implications of consumer decision-making on products as seemingly trivial as lightbulbs. Solid State Lighting: Lab Manual Link

Lab Report:  For this lab, imagine you have been charged by President Obama to investigate solid state lighting: costs, benefits, implementation, etc.  For your lab report, prepare a position paper presenting your findings, and make policy suggestions for SSL implementation.  Please address technological, economic, and public policy issues relating to SSL, based on your data.

5. Introduction to Labview (1 week) A one-week introductory Labview Lab to prepare for the wireless communication lab.  Accompanying lecture will focus on very basic programming concepts. Intro to Labview: Lab Manual Link

No Lab Report

6. Build Your Own Optical Communication System (4 weeks) Students will learn how to write a Labview program which can output data to the serial port and look at the serial port output on oscilloscopes.  Students will then build a transceiver board which will use the serial port output to drive a laser diode.  The board will also detect signal on a phototransistor and return this signal to the serial port.  The final product of the lab will be a wireless instant messaging system, which teams will use to communicate across the lab! Accompanying lectures will discuss communication languages, systems and networks, as well as the communication system hardware.

Labview Instant Messaging Program

Lab Report: For this Lab Report imagine you are a reporter with the New York Times (a technology, education, or science reporter) tasked with writing a feature article about your lab group as it completes the wireless communication lab.  Your article should include the results of the lab and MUST contain technical (and technically accurate) material.  Past this, use your creativity!!  1000-1500 words.

Final Project
For your final project, you will choose a cutting-edge field of optics research and develop a well-researched 20 minute powerpoint presentation on this topic. You will present this to the class during our scheduled final exam time slot.  Presentations should include a scientific/technical discussion of fundamentals of this field of research, as well as the potential for this work to impact our everyday lives.  Students can focus on the discussed technology's impact in Health, Medecine, Communication, Security, Defense, the Arts, Journalism, Finance, Policy, Energy, Transportation, or any other field.

Abstract:

Imaging biological samples such as tissue slices and cells without using an contrast agents is challenging due to their thin transparent nature. In the field of quantitative phase imaging (QPI) the phase shift induced by the sample on incident light is quantified with nanometer level accuracy. This not only provides high contrast images but also allows for quantitatively measuring several fundamental biological phenomenon such as growth, transport, and spatial organization. In this talk I will overview the fundamentals of QPI and provide examples of several applications.
