Paper Abstract

We present simulation results for a 5 Gb/s optically pre-amplified, differential phase shift keying communication system achieving -48.1 dBm (about 24.7 photons/bit) receiver sensitivity at 10-9 bit-error-rate and using an optical delay line interferometer made by ourselves with 1 bit delay as the demodulator. The system is also experimental tested and sensitivity of the receiver is -36.5 dBm (about 106.6 photons/bit). The experimental results have some penalty in sensitivity comparing to the results in the simulation because the 1 bit delay interferometer is sensitive to the environment such as temperature, tremble and so on. To our knowledge if the interferometer is well designed and optimized, the experimental results can correspond with the simulative results and an optically pre-amplified direct detection DPSK receiver with high sensitivity can be realized.
