A novel fully packaged balanced photoreceiver designed for 40 Gb/s DPSK applications at 1.55 µm wavelength is presented. Based on InP:Fe substrate two waveguide-integrated photodiodes with spot size converters are monolithically integrated with a distributed amplifier. This configuration leads to a high symmetry of the two optical inputs and avoids interconnection parasitics. The RF output of the photoreceiver is DC-coupled, but the design enables an interfacing to subsequent electronics without external bias-tee by using a negative bias supply at the source terminal of the integrated amplifier. A reduction of system costs and required space will be obtained by this concept. Mounted in a butterfly package, a 3 dB bandwidth of 42 GHz is achieved. RZ-DPSK experiments exhibit excellent operation of the balanced photoreceiver over a large dynamic range of optical input power up to +10 dBm. The high-power capability and the clear eye opening at low input power demonstrates the suitability for high performance core and metro systems. |
