Abstract
We report on electrically pumped GaSb-based laser diodes monolithically grown on Si and operating in a continuous wave (cw) in the telecom wavelength range. The laser structures were grown by molecular-beam epitaxy on 6°-off (001) substrates. The devices were processed in coplanar contact geometry. 100 μm × 1 mm laser diodes exhibited a threshold current density of 1 kA/cm−2 measured under pulsed operation at 20 °C. CW operation was achieved up to 35 °C with 10 μm × 1 mm diodes. The output power at 20 °C was around 3 mW/uncoated facet, and the cw emission wavelength 1.59 μm, in the C/L-band of telecom systems.
Highlights
Over the past few years, global IP traffic has been exponentially growing, driven by the explosion of requests for computing, cloud storage, and telecom
Room temperature (RT) laser emission has been demonstrated in a continuous wave mode near 1.3 μm with GaAs-based quantum-dot lasers[5,6,7] and near 2 μm with GaSbbased quantum well (QW) lasers,[8] all grown on off-axis (001) Si substrates
Full deployment of Si-photonics for telecom applications requires integrated-lasers emitting near 1.55 μm, the wavelength of choice for long-haul communication systems
Summary
Over the past few years, global IP traffic has been exponentially growing, driven by the explosion of requests for computing, cloud storage, and telecom. Room-temperature continuous-wave operation in the telecom wavelength range of GaSb-based lasers monolithically grown on Si
