We present a new DPSK receiver scheme where counter-propagating pulses collide in a saturated semiconductor optical amplifier, realizing photonically balanced single-ended detection. Decreased fluctuation of the mark level and 1.1-dB increased Q-factor is demonstrated experimentally at 22.3 Gbit/s.
