We demonstrate a novel device that demodulates both quadratures of the optical differential quadrature phase shift keying (DQPSK) format in a single interferometer by using a 2-by-4 star coupler.
We present a monolithic differential quadrature phase-shift keying (DQPSK) receiver in InP consisting of a 1 × 2 coupler, two different-length waveguides, a 2 × 4 coupler, and four photodetectors.
We have developed a dual wavelength DFB laser for the generation of a widely tunable microwave signal.
A variety of electronic functions can be accomplished in a novel way by taking advantage of the properties of domain wall motion in ferroelectric single crystals.
We describe in further detail a demonstration of a monolithic 1x2 silicon wavelength-selective switch in silicon photonics. The switching has a flexible grid with 32 pixels on a pitch of 100 GHz.
A new approach is presented for fabricating monolithic crystalline silicon tilting-mirror MOEMS devices.

We present a monolithic 1 x 2 wavelength-selective switch in silicon nitride and silicon waveguides.
We discuss telecommunication receivers in silicon optics that contain Ge photodetectors monolithically integrated with other optical elements, such as polarization splitters, phase shifters, and fi
We demonstrate a DQPSK receiver in InP with monolithic integration of an optical demodulator and four photodiodes. We show preliminary operation at 53.5 Gb/s with low polarization dependence.
