Optical phase array radar

Abstract: In an optically controlled phased array radar control information in the form of microwave frequency modulation of an optical carrier is transmitted by optical waveguide from a central processor to each of the antenna elements. Phase shifts introduced by each of the individual waveguides are then monitored to provide a compensation signal used either to regulate the phase shift or to offset the phase of the modulation applied to the waveguide at the central processor end.

Optical interfaces without light sources for base-station designs in fiber-wireless systems incorporating WDM

Abstract: Simplified optical interfaces for antenna base-stations in full duplex millimeter-wave fiber-wireless systems are realized by reusing the optical carrier used in the downstream transmission, for upstream data transmission. Results from an experimental full duplex link operating at 34-38 GHz with a 155 Mb/s BPSK data stream over 10 km of optical fiber are presented.

Gigabit single-mode fiber transmission using 1.3-µm edge-emitting LEDs for broad-band subscriber loops

Abstract: This paper describes gigabit single-mode fiber transmission using 1.3-μm edge-emitting LED's for broad-band subscriber loops, focusing on a method of calculation for maximum transmission distance and 1.2-Gbit/s and 600-Mbit/s transmission experiments. Gigabit single-mode fiber transmission is necessary for subscriber loops, especially in broad-band ISDN and optical CATV systems. Edgeemitting LED's are excellent light sources because of their high power launched into the fiber compared with surface-emitting LED's, and currently lower cost and higher reliability than laser diodes. The maximum transmission distance is carefully estimated by taking into account the wavelength dependence for both chromatic dispersion and loss of the single-mode fiber, and the possibility of gigabit transmission near the dispersion free wavelength 1.3 μm, is confirmed. Encouraged by the above results, we demonstrate 1.2-Gbi,t/s 10-km and 600-Mbit/s 20-km transmission experiments using a newly developed 1.3-μm edge-emitting LED and a new driver circuit with a simple response compensation circuit. These results show the proposed calculation method and the LED response compensation circuit to be powerful tools for the realization of low-cost gigabit single-mode fiber transmission using edge-emitting LED's.

Key building blocks of a silicon photonic integrated transmitter for future detector instrumentation

Abstract: The data throughput of future detector readout systems is ever increasing. We propose a high-performance optical link, based on silicon photonics and wavelength-division multiplexing (WDM) technology, to cope with ultra-broad bandwidth requirements. The key components of the proposed optical link are monolithically integrated transmitter units, each one integrating multi-channel on-chip Echelle grating (de-)multiplexers and Mach-Zehnder modulators (MZMs). In our current design, each transmitter unit consists of four MZMs, which corresponds to four transmission channels with distinct optical carrier wavelengths, a common optical demultiplexer and a common optical multiplexer. In this paper, we present the design and experimental results of all these building blocks as well as a first transmission experiment. Additionally, experimental results of a thermal modulator to be used in a future design for working point control are presented.
