Abstract
InGaAs photodetectors have been fabricated having a packaged RC plus transit-time-limited bandwidth of 20 GHz and a fibre-coupled responsivity of 0.55 A/W. Using a directly modulated InGaAsP diode laser, the photodetector optical frequency response was measured 3 dB flat to 17 GHz, the bandwidth limit of the laser.
