Yee-Loy Lam

Yee-Loy Lam, Chief Operating Officer / Chief Technology Officer

Lam Yee Loy is COO/CTO of DenseLight Semiconductors, and one of four co-founders of the company.

Prior to founding DenseLight Semiconductors, Dr. Lam was a professor in the Nanyang Technological University (NTU) of Singapore from 1990 to 2000, leading a team of about 150 staff in the Microelectronics Division. He also served in a concurrent appointment with the Office of the University’s President, contributing significantly to NTU’s position as the University of the Industry. Dr. Lam was also invited to sit on the NTU Council (Univ. Board of Governors), representing all academic staff, from 1996 to 1998.

Before joining NTU, Dr. Lam headed the R&D Department in Rank O’Connors from 1985 to 1989, establishing the manufacturing operations for building automation products.

Dr. Lam’s area of technical expertise is in optoelectronics, fiber-optics sensors, and photonics systems applications. Recognising and identifying photonics sciences as a critical industry driver, he played a key role in the surge of photonics-related business interest to Singapore. This included introducing postgraduate courses in photonics, establishing the formation of the Singapore Center of Photonics Excellence, and serving as the Symposium Chairman for the inaugural SPIE conference ISPA-99 & ISMA 2000.

Dr. Lam received his Bachelors in Engineering with First Class Honours in Electrical and Electronic Engineering (NTI 1985 Pioneer Class), and his Masters in Industrial Engineering, from the National University of Singapore (NUS). He also holds a MSE degree and a Ph. D. in Electrical Engineering from the University of Michigan, USA.

Yuen-Chuen Chan

Yuen-Chuen Chan, Vice President Engineering (Photonics)

Prior to co-founding DenseLight Semiconductors, Dr Chan was professor in NTU and was the coordinator of the university's Photonics Research Group. He managed the university's photonic devices fabrication Lab and within a short span of 2.5yrs, expanded facilities into a cluster to service industrial programs and published more than 180 scientific and industrial papers.

Dr Chan brings deep expertise in industrial device fabrication development, component structural design, opto-electronic epitaxial and grating re-growth. With experience dating back to University of Tokyo, Dr Chan did the then pioneering work developing the tensile strained quantum well growth technique on GaAs for polarization insensitive optical modulation. In NTU, he won many industrial funding programs and led large-scale project teams for photonics device research and manufacturing fabrication. These programs include epitaxial growth by MBE, MOCVD and LPE and characterization of quantum well structures, laser diodes, optical modulators, photo-detectors and PICs. His accomplished experience in leading fabrication teams resulted in DenseLight owning significant structure fabrication competence IP and the capability to rapidly rollout PIC product.

Dr Chan pursued his education as a distinguished Public Service Commission Monbusho Scholar and received his B.Eng, M.Eng and PhD degrees in Electronics Engineering majoring in Optoelectronics, all from the University of Tokyo in Japan.
