Dan Cohen, PhD

Research Advisor (retired)

Research Advisor (retired) with several decades of experience inventing and developing InP and GaN based laser diodes and photonic integrated circuits for communication, biochemical sensing, data storage, solid state lighting, displays and LIDAR. Expertise includes device design, fabrication, testing and analysis. Recent projects have included high power and high efficiency lasers, VCSELs, and ultraviolet lasers.

Michael Iza

Principal Development Engineer

Principal Development Engineer responsible for SSLEEC's MOCVD lab. Recent projects focus on development of novel nitride based devices and materials for applications in solid state lighting. Responsibilities include supervision of MOCVD equipment and facilities as well as all safety and training requirements.

Arturo Juan (He/Him/His)

Graduate Student Researcher, Materials

Arturo Juan earned his bachelor’s degree in chemical engineering from the University of Southern California, then earned his master’s degree in electrical and computer engineering from UCSB. He worked in industry prior to entering the Materials PhD Program. Juan is advised by Steven DenBaars, a distinguished professor of materials and electrical and computer engineering. The focus of his research is on the epitaxial growth, processing, and characterization of wide-bandgap semiconductors for optoelectronic devices. According to Juan, working to improve the efficiency of materials that emit light could pave the way, for next-generation technologies having applications in optical communication, sensors, lighting, and quantum computing.
