A 38-47.8 GHz quadrature voltage controlled oscillator (QVCO) in InP HBT technology is presented. The measured output power is - 15 dBm.
Using substrate transfer processes, we have fabricated heterojunction bipolar transistors with submicrometer emitter-base and collector-base junctions, minimizing RC parasitics and increasing f(max
Constructional details are given of the installation, with descriptions of the rectifiers, stabilizer, and ancillary control equipment.
We propose a 4D-CMA feedback for butterfly filter adaptation enabling separation of channel compensation and polarization demultiplex.
This lecture will be presented as part of the AT&T Bell Laboratories Department 55111 Affirmative Action Program.
We present extensive numerical simulations of an optical link deploying four electro-absorption modulated lasers (EMLs) at 25 Gb/s over up to 40 km of standard single-mode fiber.
We demonstrate 4¿¿10-Gb/s coarse wavelength-division multiplexed (CWDM) transmission using commercial vertical cavity surface emitting lasers (VCSELs) over ⫠45 km of standard single-mode fiber
We demonstrate four-channel wavelength-division multiplexing (WDM) transmission over conventional fiber at per-channel rate of 40 Gbit/s.
We demonstrate a four-channel 40-Gb/s-per-channel time- and wavelength-division-multiplexed PON over a 42-km, 64-split fiber plant using optical duobinary modulation.
We demonstrate the transmission of 4 channels at 43Gb/s over a record 525km unrepeatered distance using PMD-tolerant and spectrally efficient PDM-RZ-BPSK modulation combined with a coherent receive
