<p>A single-crystal, monolithic, tandem, multicolor optical transceiver device (100) is described, including (a) an InP substrate (102) having upper and lower surfaces, (b) a first junction (104) on the upper surface of the InP substrate, (c) a second junction (106) on the first junction. The first junction is preferably GaInAsP of defined composition, and the second junction is preferably InP. The two junctions are lattice matched. The second junction has a larger energy band gap than the first junction. Additional junctions (108) having successively larger energy band gaps may be included. The device is capable of simultaneous and distinct multicolor emission and detection over a single optical fiber.</p> |
