High-Performance InP-Based Photodetector in an Amplifier Layer Stack on Semi-Insulating Substrate

Lateral current injection GaInAsP/InP laser on semi-insulating substrate for membrane-based photonic circuits.

A room-temperature pulsed operation was demonstrated using lateral current injection-type lasers composed of a 400-nm-thick GaInAsP core layer with compressively strained 5 quantum wells. A threshold current of 105 mA and corresponding density of 1.3 kA/cm(2) (260 A/cm(2) per well) were obtained with the stripe width of 5.4 microm and the cavity length of 1.47 mm. A fundamental transverse mode ...

Electrical conduction in annealed semi-insulating InP

High-bandwidth uni-traveling carrier waveguide photodetector on an InP-membrane-on-silicon platform.

A uni-traveling carrier photodetector (UTC-PD), heterogeneously integrated on silicon, is demonstrated. It is fabricated in an InP-based photonic membrane bonded on a silicon wafer, using a novel double-sided processing scheme. A very high 3 dB bandwidth of beyond 67 GHz is obtained, together with a responsivity of 0.7 A/W at 1.55 μm wavelength. In addition, open eye diagrams at 54 Gb/s are obs...

Millimeterwave INP DHBT power amplifier based on poweroptimized cascode configuration

This letter describes the use of a power-optimized cascode configuration for obtaining maximum output power at millimeter-wave (mm-wave) frequencies for a two-way combined power amplifier (PA). The PA has been fabricated in a high-speed InP double heterojunction bipolar transistor technology and has a total active emitter area of 68.4 lm2. The experimental results demonstrate a small signal gai...
