Yee-Loy Lam

Yee-Loy Lam, Chief Technology Officer

Dr Lam received his B.Eng in Electrical and Electronic Engineering (First Class Honors) and his MSc in Industrial Engineering from the National University of Singapore., and his MSE and Ph. D. in Electrical Engineering from the University of Michigan, USA.

In 1985, he began his career with the Singapore unit of a UK-based multinational company in developing building automation products and subsequently establishing its manufacturing operations. From year 1990 to 2000, he was a professor in the School of Electrical and Electronics Engineering of the Nanyang Technological University of Singapore. Notable appointments in the University included Head of Microelectronics Division, Principal Staff Officer to the University’s President, and member of the NTU Council (University’s Board of Governors).

In Year 2000, he led the founding of DenseLight Semiconductors and raised a US$31.2 million VC Round from 3i-PLC (to establish a InP Optoelectronics Wafer Fab), and subsequently in 2003-2004 (despite negative market sentiment post 2002 photonics-crash) he raised US$8.6M to realize self-sustaining business operations by 2005 with revenue from products and services for its photonics sensing and test customers. He continued to serve as DenseLight CTO after the company was acquired by POET Technologies in May 2016.

Dr. Lam’s area of technical expertise is in optoelectronics, fiber-optics sensors, and photonics systems applications, and has contributed to some 300 publications and 60 patents. For the past 25 years, he has been a significant participant in a number of key initiatives to promote the growth of photonics-related research and industrial development in Singapore; and he is still doing so today.

Yuen-Chuen Chan

Yuen-Chuen Chan, Vice President Engineering

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.
