We investigated hybrid-integration of InP semiconductor optical amplifier on silicon photonics chip using flip-chip bonding, and achieved in-line optical amplification of 10 dB. Silicon 1×8 splitter and selector are fabricated and operated with on-chip loss-compensation.
We demonstrate chalcogenide glass photonic crystal waveguides and their high optical nonlinearity, for the first time. Self-phase modulation and four-wave mixing are observed in a 400-mum-long device without two photon absorption.
We propose a novel configuration for a tunable optical dispersion compensator (TODC) with increased bandwidth. We demonstrate 40-wavelength channelized compensation for 400-ps/nm chromatic dispersion with a 40-GHz bandwidth using the proposed TODC.
In this paper, we illustrate the performance evaluation methods for optoelectronic circuit boards (OECBs). Here we report the details of the evaluation techniques for a bidirectional OECB developed to operate at 10 Gbps using a flip chip SMT optical transceiver. The evaluation techniques include DC and high speed optical characterization of individual component as well as at interconnect level. Performance...
We demonstrate a PDM-QPSK modulator operating at 100-Gb/s. Two QPSK modulators and a polarization beam combiner are integrated using a hybrid assembly technique with silica PLCs and LiNbO3 phase modulators.
We successfully demonstrate the polarization-insensitive operation of an MZI-based LN switch with PLC-integrated polarization beam splitter/combiners. The switch functions for both polarizations with a PDL of 0.1 dB and a switching speed of 40 ps.
We report the development of a low cost, simple optical circuit board (OECB) using large core multi mode polymer waveguide on FR4 printed circuit board (PCB). The design of this OECB uses only a 45deg-ended waveguide to couple and decouple the optical signal directly between the optical devices and the waveguide. The 45deg mirror is formed using excimer laser process on a multi mode waveguide with...
We developed a hybrid integrated tunable laser based on waveguide ring resonators using passive alignment technology. A compact chip having a wavelength locker, stable high output power and excellent mass-productivity was achieved.
A simple tunable laser consisting of a SOA mounted on Si substrate with silica waveguide resonated-ring-resonator was proposed. An excellent coupling loss of 0.41 dB between the waveguide and SOA enables fiber output power of more than 16 dBm.
The purpose of the paper is to reveal the influence of higher-order mode of VCSEL emission on the coupling efficiency between VCSEL and waveguide. Firstly, we measured and simulated the coupling efficiency between VCSEL and 50SI-MMF and pointed out the influence of higher-order of VCSEL emission. Then, we measured the VCSEL power intensity and analysed the dependency of higher order transverse-mode...
A novel wavelength-selective switch is proposed and demonstrated. The switch has a 1 /spl times/ 4 transversal filter configuration that includes AWGs and thermo-optic phase shifters, and can route input light at an arbitrary wavelength to arbitrary outputs with no loss variation. We confirmed its operating principle and obtained an average loss of 5.7 dB and an average extinction ratio of 27 dB.
