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… (More)
The dynamics of the micromachined-tunable surface-emitting laser are derived from amplitude modulation response. The dependence of resonance frequency on bias current and wavelength is reported. The device shows 3-dB modulation frequency above 6 GHz.
Several Applications for tunable laser diodes have strict constraints in terms of overall power consumption. Furthermore, the implementation in harsh environments with large temperature fluctuations is necessary. Due to the constraint in power consumption, the application of active cooling might not be an option. For this reason we investigate the… (More)
We present a surface micromachined electro-thermal as well as electro-statical tunable Fabry-Pérot filter for on wafer mass production. With insertion losses < 1.4 dB (from standard single mode fiber (SSMF) to SSMF) and a tuning range of 112 nm.
We report an InP based vertical cavity surface emitting lasers (VCSEL) achieving lasing operation between 1529 nm and 1646 nm. This optically-pumped VCSEL includes a widegain bandwidth active region based on InAs quantum dashes and wideband dielectric Bragg mirrors. Based on a wedge microcavity design, we obtain a spatial dependence of the resonant… (More)
