We present a monolithic 50 Gb/s DQPSK receiver on hybrid silicon, consisting of delay interferometers, phase shifters, balanced InGaAs p-i-n photodetectors, and MIS capacitors. Preliminary measurements of stand-alone PDs show 23–28 GHz 3dB bandwidth.

The 3–4μm wavelength range is of key technological importance for a wide range of applications. As a consequence of the strong fundamental C-H stretch mode that occurs at around 3.3μm, the detection of many important hydrocarbon species has maximum sensitivity (potentially ∼ parts per trillion) in this range. This leads to many important applications in various areas, for example, clinical diagnostics, process monitoring and remote detection of oil and gas deposits. This short wavelength IR region is also of interest for several defence and security applications as well as free-space “last mile” telecommunications. The unsuitability of the “conventional” InGaAs/AlInAs materials system for high performance QCL sources in this short wavelength range has led to significant interest in new QCL materials with very high conduction band offsets (ΔEc) based on III-V antimonides such as InAs/AlSb/InAs (ΔEc ∼ 2 eV) and InGaAs/AlAs(Sb)/InP (ΔEc ≤ 1.6 eV). Very recently, significant progress has been made in the development of these “short wavelength” QCLs operating in the close vicinity of λ ∼ 3 μm. In our work, we have focussed on the InGaAs/AlAsSb system, which provides both a very high ΔEc that can comfortably accommodate the high energy intersubband transitions required, and lattice-matched compatibility with InP. This latter feature is extremely important as it greatly simplifies optical waveguide development and facilitates advanced device fabrication. Recent highlights of our research on InGaAs/AlAs(Sb) QCLs have included strain compensated QCL growth, the shortest wavelength room temperature InP-based QCL operation at around 3.1μm [1] and novel high performance structures at λ ∼ 4.1 μm with selectively incorporated AlAs barriers in the active regions.

As in the case of quantum information and communication, in the field of quantum imaging entanglement represents an invaluable resource. Processes such as parametric down-conversion (PDC) and four-wave mixing provide natural sources of quantum entangled beams endowed with spatial entanglement properties that are useful in quantum imaging. We will review these well known features in the case of PDC, and the technique which allows for an imaging with a sensitivity beyond the standard quantum limit, which has been theoretically predicted [1] and experimentally demonstrated [2].

Stimulated Raman scattering (SRS) in optical fibers is a well-known method of signal amplification in Raman amplifiers and lasers for the generation a wide range of wavelengths. Today, there are a large number of applications requiring high power beams at wavelengths longer than 2 μm, and non-oxide based glass fibers with low phonon energies and high infrared transparency are very attractive for applications in this region. Fluoride, tellurite, and chalcogenide fibers are the best choices for this purpose. An important issue in high power fiber based Raman amplification (RA) is the heat generated inside the active medium due to the quantum defect between the pump and the amplified wavelengths. The increase in the temperature of the laser medium can detrimentally affect laser performance, by degrading the quality of the amplified beam, causing a decrease in the efficiency of the process, thermal lensing and self focussing. The cooling of the laser medium is a key issue for improving laser performance and increasing the laser's lifetime. Mitigation of the heat generated in Raman lasers using coherent anti-Stokes Raman scattering has been suggested in Ref. [1].

We demonstrate bandwidth provisioning in a robust and asynchronous optical CDMA system that implements polarization insensitive transmitter and wavelength-aware receiver. The system accommodates heterogeneous gigabit Ethernet traffic, and the performance is characterized by power penalty from normalized multiple access interference power.
