摘要
For the first time a vertical-cavity surface-emitting laser (VCSEL) with singlemode wavelength tuning over 74 nm in the range of 1.55 mu m and a wavelength tuning speed of similar to 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 SiO(x) and SiN(y) deposited with low temperature (<100 degrees 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 side-mode suppression ratio is >40 dB.
