ABSTRACT: For the first time a vertical-cavity surface-emitting laser (VCSEL) with singlemode wavelength tuning over 74 nm in the range of 1.55 µm and a wavelength tuning speed of ~200 kHz is demonstrated. The wavelength tuning is achieved with the electro static actuated of a mirror membrane, fabricated with surface micromachining. The mirror membrane consists of the dielectric materials SiOx and SiNy deposited with low temperature (< 100 °C) plasma enhanced chemical vapour deposition. The maximum fibre-coupled optical output power of the VCSEL is 1.8 mW and >1 mW over the entire tuning range. The sidemode suppression ratio is >40 dB.

ABSTRACT: For the first time a vertical-cavity surface-emitting laser (VCSEL) with a single-mode wavelength-tuning over 102 nm in the range of 1550 nm is demonstrated. The fiber-coupled optical output power has a maximum of 3.5 mW and is > 2 mW over the entire tuning range. The sidemode suppression ratios are > 45 dB. The wavelength tuning is achieved with the micro-electro mechanical actuation of a mirror membrane fabricated with surface micro-machining for on-wafer mass production. The mirror membrane consists of low cost dielectric materials (SiOx/SiNy) deposited with low temperature (< 100°C) Plasma Enhanced Chemical Vapor Deposition (PECVD).
