  • Publication number: 20020076173
    Abstract: Fiber optic transmitter and receiver electrical elements are implemented on separate vertical boards in fiber optic modules. A single optical block implements lenses and reflecting surfaces to minimize manufacturing costs. In one embodiment the receiver and transmitter are mounted to receive and transmit vertical boards respectively to nearly face each other but being offset to avoid optical cross talk. In a second embodiment, receiver and transmitter are mounted parallel with the printed circuit boards to save additional space. The vertical boards have ground planes to minimize electrical cross talk. A shielded housing provides further shielding for EMI. Manufacturing steps of the fiber optic transceiver are disclosed which provide reduced manufacturing costs.

  • Publication number: 20020054618
    Abstract: Modulated integrated optically pumped vertical cavity surface emitting lasers are formed by integrating an electrically pumped semiconductor laser and a vertical cavity surface emitting laser (VCSEL) together with a means of direct modulation of the electrically pumped semiconductor laser. In the preferred embodiments, the electrically pumped semiconductor laser is a type of folded cavity surface emitting laser (FCSEL). In a number of embodiments, the FCSEL is partitioned into two sections by a gap in material layers. In these embodiments, one section of the FCSEL is biased so as to maintain the generation of photons at a constant power level to pump the optically pumped VCSEL while the second section of the FCSEL is used for modulation and causes the optically pumped VCSEL to be modulated above the threshold. In another embodiment, an electric-absorption modulator is sandwiched between an electrically pumped FCSEL and an optically pumped VCSEL.

  • Patent number: 6115398
    Abstract: Automatic power control (APC) of a semiconductor laser array is achieved by monitoring the backward emission emitted by a plurality of semiconductor devices which compose the semiconductor laser array. The drive signal to the laser is adjusted based on the detected emissions. A photosensor mounted in a submount, to which the semiconductor laser array is mounted, is positioned to receive a photocurrent from the backward emissions. A sweeping injection current across the laser array provides for the sequential detection of the backward emission and thus provides for automatic power control (APC).

  • Patent number: 6091754
    Abstract: A VCSEL (113) having a first and a second stack of distributed Bragg reflectors (120, 116) and an active region (118) is formed. Conductive layers (108 and 109) having an opening is formed on the second stack of distributed Bragg reflectors (116). A first region (104), a second region (106), and a third region (108) are formed in the opening of the conductive layer (108), thereby providing a contact to both the second stack of distributed Bragg reflectors (116) and to the first region (104). An insulative layer (220) is disposed on the substrate (124), thereby insulating the second region (106) from the conductive layer (108). A conductive layer (134) having second opening disposed substantially overlying the first opening, thereby electrically coupling the third region (108) to the conductive layer (134) with the second opening allowing a light (121) to pass.
