Short-wavelength MEMS-tunable VCSELs.
We present electrically-injected MEMS-tunable vertical-cavity surface-emitting lasers with emission wavelengths below 800 nm. Operation in this wavelength range, near the oxygen A-band from 760-780 nm, is attractive for absorption-based optical gas sensing. These fully-monolithic devices are based on an oxide-aperture AlGaAs epitaxial structure and incorporate a suspended dielectric Bragg mirro...
متن کاملSwept Wavelength Testing:
In a swept-wavelength measurement system, the wavelength of a tunable laser source (TLS) is swept continuously at a constant rate throughout the desired tuning range, while the device under test (DUT) is monitored simultaneously for its wavelength-dependent optical properties. Given an ideal continuously tunable laser – one that does not exhibit any discontinuities in wavelength, or sudden chan...
متن کامل22-Gb/s Long Wavelength VCSELs.
1.55-microm vertical cavity surface-emitting low-parasitic lasers show open eyes up to 22-Gb/s modulation speed. Uncooled error-free operation over a wide temperature range up to 85 degrees C under constant bias conditions is demonstrated at 12.5-Gb/s data rate. At these fixed bias conditions the laser characteristics are practically invariant with temperature. These are the highest data-rates ...
متن کاملRapidly swept, ultra-widely-tunable 1060 nm MEMS-VCSELs.
Demonstrated are 1060 nm microelectromechanical-systems-based tunable vertical-cavity surface-emitting lasers (MEMS-VCSELs) with a 100 nm continuous tuning range under repetitively scanned operation at rates beyond 500 kHz and a 90 nm continuous tuning range under static operation. These devices employ a thin strained InGaAs multiple quantum well active region integrated with a fully oxidised G...
متن کاملHigh-Speed InP-Based Long-Wavelength VCSELs
The rapid growth of internet and cloud computing applications drives a huge demand for bandwidth capacity in communication networks, while power consumption, cost, and space density must scale down. This growth leads to an increase in the size of data centers (longer optical links), and of the fibers’ channel data rate, rooted in Moore’s Law. Until now, multi-mode fibers (MMF) have been largely...
