We present a compact design for flattening the passband of a waveguide grating router theoretically without excess loss or chromatic dispersion.
A 300nm broadband visible continuum has been generated in a 1.8m length of microstructured fibre pumped at 532nm by 0.8ns pulses from a frequency-doubled passively Q-switched Nd:YAG microchip laser
A new class of coaxial cavity filters with low-profile suitable for base transceiver station applications is proposed.
A novel tunable dispersion compensator (TDC) with ±500 ps/nm tuning range and bandwidth support for 40-Gb/s signals is described.
Compact monolithic integrated differential VCO's operating in W-band were realized using InP-based HBT's.
We present a new design for a digitally tunable laser using two waveguide grating routers wirh different free spectral range.
We have utilized excitonic electrorefraction in reverse-biased InGaAsP/InP quantum well heterostructures to produce directional coupler switches with device lengths under 600microns operating at 1.
We present a novel InP differential quadrature phase shift keying (DQPSK) modulator design comprised of two electro-absorption modulators in a three-arm interferometer.
Resonator antennas based on Fabry-Perot (FP) cavities are low-profile directive antennas widely studied for moderate or high-gain applications.
