Photoluminescence PL Setup (Custom)
The Photoluminescence setup is on the same optical table as the Hologaphic Lithography setup.
This custom setup is used for materials characterization including crystal growth quality and gain region/quantum well growth, or semiconductor alloy ratio. Multiple laser sources are available - including the He-Cd laser also used for Holography, via a flip-down mirror.
Light is delivered in free-space and collected by optical fiber, and analyzed by a USB spectrometer.
Pump Lasers Available
- 325nm He-Cd - single mode, spatially filtered
- Flip-down mirror to divert light from holography setup to PL delivery.
- 405nm Diode Laser
- 660nm Diode Laser
- Ocean Optics USB2000+
- 340nm to 1025nm wavelength acquisition, through multi mode optical fiber
- Raman spectrometer
