Abstract
An InAIAs/InGaAs superlattice (SL) multiplication layer operating at an IC-power supply voltage was realized by introducing strain into the SL. Using this SL as an absorption and multiplication layer, edge-coupled InAIAs/InGaAs SL avalanche photodiodes with waveguide structures were demonstrated. An avalanche multiplication factor larger than 10 was achieved at a bias voltage of less than 7V. A wide 3 dB bandwidth of 8 GHz was obtained at a multiplication factor of 3 and a wavelength of 1.3 μm.
