The high capacity transport infrastructure that underpins today's Internet utilizes optical wavelengths both to provide high capacity transmission by means of multiplexing many wavelengths, each carrying as much as 100 Gb/s on a single wavelength, bu

The dependence of the coupling strength of titanium-diffused lithium niobate directional couplers upon fabrication parameters and guided wavelength has been investigated. Measurements of the coupling strength as a function of interguide separation ha

We propose and demonstrate a new integrated-optic TE/TM splitter using a polarization-selective Ti:LiNbO(3) directional coupler. By application of appropriate voltages, either polarization can be selected (cross talk will be below -30 dB) or both TE

Using tensile‐strained InGaAs/InGaAsP multiple quantum well material to increase the gain bandwidth, we demonstrate a tuning range of 74.4 nm with sidemode‐suppression ratio of ≳25 dB and as high as 34 dB in a broadly tunable vertical‐coupler

A new mechanism for polarization rotation in rib waveguides is suggested and demonstrated in InP waveguides. The polarization rotation is achieved by loading a rib waveguide in a periodic asymmetric way. Complete TE↔TM conversion, with only 2–3 d

Throughout the evolution of the field of integrated optics/photonic integration, periodic structures have played a key role. The early grating couplers, fine pitch Bragg gratings, acousto-optic and electro-optic phase-matched TE↔TM conversion, peri

Nonlinear Guided Waves and Their Applications.
After years of research, much anticipation, and some frustration, integrated photonic components are now key enablers for a new generation of commercial optical systems. In applications, including digital modulators and polarization scramblers in und
