MICHAEL C.Y. HUANG, Y. ZHOU AND CONNIE J. CHANG-HASNAIN* Department of Electrical Engineering and Computer Sciences, University of California at Berkeley, California 94720, USA *e-mail: cch@eecs.berkeley.edu Published online: 1 February 2007; doi:10.1038/nphoton.2006.80 Semiconductor diode lasers can be used in a variety of applications including telecommunications, displays, solid-state lighting, sensing and printing. Among them, vertical-cavity surface-emitting […]
Abstract—We report an electrically-pumped 1050 nm micro-electro-mechanically-tunable vertical-cavity surface- emitting-laser (MEMS-VCSEL) with a record single-mode, continuous, mechanical tuning range of 73.2 nm with hig output power and low threshold current performance, which is suitable for next generation swept-source optical coherence tomography (OCT) imaging and sensing applications. Keywords—Vertical-cavity surface-emitting laser, Optical Coherence Tomography, Optical microelectromechanical (MEMS) […]
