Interested graduate and undergraduate students at Cal Poly Pomona or nearby universities should contact Prof. Ertan Salik. Please send your brief statement of interest, your transcript, and a short CV showing your previous related experience, if any. After the initial training period, there may be funding available especially for summer. Currently, we have openings for the following projects:

Fiber Optic Biosensor for Protein, Toxin, and Bacterial Detection: This project includes fabrication of tapered optical fibers, their testing using optical spectrum analyzer and broadband/laser sources. Also, microfluidic channels will be fabricated and fiber sensors will be embedded in them. Some tasks will include CAD design of microfluidic channels, electronic wiring, labview programming and operation. Fiber optic modeling with Optiwave mode solver can be done, too.

Fluorescent Microscopy on a Cell Phone: Inspired by my current host Aydogan Ozcan at UCLA, this project aims to develop a portable fluorescent microscope on a cell phone. There will some CAD design, and 3-D printing for a cell phone attachment, which will house LEDs and a simple lens. The student will also learn how to label particles and cells for imaging.

SMS Sensors for Temperature/Strain Sensing: Single-mode-multimode-single-mode (SMS) sensors are very simple to fabricate, yet very sensitive to detect temperature and strain. Projects available to analyze the SMS sensor data to show the best limit of detection considering possible noise sources. Some computation tools will be used for analysis, such as Igor Pro, Mathematica, or Matlab. Will need to learn how to fabricate the sensors with fiber splicing and characterization with light sources and spectrum analyzer.

Fiber Lasers for the best limit of detection: A fiber sensor ( tapered fiber sensor, or SMS sensor) can be inserted in a laser loop to obtain better detection limit. The project will include building a fiber laser in a temperature controlled environment, testing sensors inserted in the laser loop, analyzing data to determine the best limit of detection. Some statistical and computational methods will be utilized. The project has both experimental and theoretical/computational aspects.
