Optical and electrical properties of bandgap shifted 1.55-/spl mu/m laser diodes

Summary form only given. In this paper we report on optical and electrical properties of 1.55-/spl mu/m InGaAsP-InP QW waveguide laser diodes blue-shifted using high-energy ion implantation and rapid thermal annealing. We demonstrate that, after shifting, waveguide losses are not increased and there is no significant change in the electrical properties of electroabsorptive modulators and laser diodes. Thus, this is a very attractive technique for achieving inexpensive and reliable photonic-integrated circuits (PIG).NRC publication: Ye

Eight-wavelength DBR laser array transmitter for WDM applications

We report on the design, growth, fabrication and characterization of monolithic wavelength division multiplexed (WDM) laser array transmitter and receiver chips produced by the Canadian Solid State Optoelectronics Consortium. The transmitter chip includes multiple, discrete wavelength, distributed Bragg reflector (DBR) laser diodes monolithically integrated with waveguide combiners fabricated using an InGaAs/GaAs heterostructure. The corresponding wavelength demultiplexer unit is based on a Rowland circle grating spectrometer monolithically integrated with a metal-semiconductor-metal (MSM) detector array fabricated on an InGaAs/AlGaAs/GaAs heterostructure. The epitaxial layer wafers for both transmitter and receiver modules were grown in single molecular beam epitaxy (MBE) runs.NRC publication: Ye

Hybrid integration of an eight-channel WDM transmitter and receiver module at 980 nm

The inherent information bandwidth of optical fibers between the wavelengths 1.3 and 1.6 micrometers is in the terahertz range. One obvious way to exploit this bandwidth is to use wavelength-division multiplexing (WDM). The Canadian Solid State Optoelectronics Consortium (SSOC), an association of industry, university, and federal government research laboratories, has been developing the component technologies required to demonstrate the operation of an eight channel WDM system. This paper discusses the integration of the transmitter (Tx) and the receiver (Rx) modules using a thin film process on alumina substrates. The Tx module contains a fully integrated eight channel DBR laser array with two quad-laser driver circuits. The signal from the lasers is combined into a single waveguide and is then carried off-chip via a polarization maintaining optical fiber. The Rx module is made up of an integrated receiver circuit, and a series of amplifiers providing the gain required for signal and clock recovery. The receiver circuit consists of an echelle grating which disperses the eight distinct wavelengths into a bank of InGaAs metal-semiconductor-metal (MSM) detectors. Some of the performance parameters of the Tx and Rx modules are presented.NRC publication: Ye
