A long-wavelength monolithically integrated high-sensitivity single-channel photoreceiver and a two-channel receiver array which requires only a single 5-V power supply are demonstrated. Both devices were fabricated using Be ion implantation and MOVPE grown crystals. The single-channel photoreceiver offers a sensitivity of -33.6 dBm for 622 Mb/s together with wide dynamic range of 21.6 dB. A two-channel receiver array exhibited a sensitivity of -32 dBm and a dynamic range of 22 dB with a well-suppressed crosstalk level below -30 dB.<>
