Pasadena City College
Laser Technology Program
The first PCC LaserTech student cohort begins this Fall 2021 semester! Students completing the program in Laser Technology will learn the scientific principles of optics, fiber-optics, and lasers. Laser and Photonics Technology instructors lead hands-on, laboratory-driven classes, utilizing state-of-the-art industrial equipment, based on the industry-guided photonics curricula written by industry professionals. In addition to laboratory skills, students are offered one-on-one support and career advice, including résumé and LinkedIn profile building.
Our newsletter is currently on hold.

“Versatile Diffractive Flat Optics”
Prof. Rajesh Menon,
Dir. Lab. for Optical Nanotechnologies
Univ. Utah, Salt Lake City
Traditional refractive lenses are bulky owing to their curvature. Flat diffractive lenses can overcome this difficulty, but traditional diffractive optics have limited reach, primarily due to chromaticity. Recently, we have shown that by treating the “imaging” phenomenon as simply information transfer from the object to the image plane, the spatial distribution of the phase in the focal plane can be an arbitrary function.
Using this concept, we have shown that allowing the phase in the image plane of a flat lens to be a free parameter enables imaging properties of unprecedented versatility in flat, multilevel diffractive lenses (MDLs).
Our research group has demonstrated binary multi-level diffraction lenses in three high performance categories: super-achromatic lenses in three wavelength regions (8-12um 0.45-1 um, 1.5-150 um), high NA of 0.9 of at 0.85um, and extreme depth of focus (5mm to 1200mm).
We believe that our inverse-designed flat MDLs, which can be manufactured using low-cost imprinting techniques, could prove widely applicable—especially where weight and restricted form factor are important considerations, as in aerospace and airborne imaging as well as augmented and virtual reality displays.
