Record sensitivity, in full-duplex operation at 155 mbit/s, of a BRS/ridge in-line transmit receive device

Summary form only given. For extensive implementation of fiber-to-the-home (FTTH) networks, low-cost optoelectronic modules featuring bi-directional transmission (transceivers) are required. It is commonly believed that the manufacturing cost-down of the transceivers should be achieved by assembling optoelectronic components on one substrate. Typical examples are the planar light wave circuit platform technology and photonic integrated circuits (PICs). In-line type PIC transceivers, integrating a laser and a photodiode along a straight guide, are very attractive because they are very compact and can be fabricated using well-established industrial technology. We report the system performances at 155 Mbit/s, of an in-line transceiver prototype module emitting at 1.3 /spl mu/m and receiving at 1.55 /spl mu/m Without signal subtraction, a full-duplex sensitivity as low as -21.5 dBm was measured.
