We present theoretical and experimental results on an analog-fiber optic link using commercially available, or so, optoelectronic devices. The directly modulated experimental link operates at 850 MHz and an improvement of 11.5 dB on insertion loss has been obtained using passive reactive networks. The experimental optical link has shown an electrical insertion loss of -8 dB. The respective contributions of emitter and receiver modules have been clearly pointed out. [ABSTRACT FROM AUTHOR]

We present the design and realization of a 1×4 switching matrix, based on an electro-optical directional coupler. This matrix is devoted to true time delay systems. It is characterized by an original topology that reduces global power consumption down to 20 mW. Fiber-to-fiber losses are 15 dB, and the crosstalk is lower than -20 dB. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 18: 243–246, 1998. [ABSTRACT FROM AUTHOR]

High-density low-loss dielectric optical interconnection is demonstrated on a monomode optical waveguide compatible with microelectronics technology. Low-loss self-aligned integrated mirrors (SAIM) on a dielectric (polyimide-silicon nitride-polyimide) optical waveguide have been fabricated. Optimization of the reactive ion etching process has been made in order to obtain vertical, homogeneous etched sidewalls. Using such a process, 45° integrated mirrors present reflection losses of 0.6 dB at a 830-nm wavelength (quasi-TE mode). [ABSTRACT FROM AUTHOR]

InGaAsP/InP micro-waveguides are fabricated by a deep (>3 μm) Reactive Ion Etching. The devices losses are measured by the Fabry–Perot technique for guide width contained between 10 μm and 0.5 μm. The measured losses range from 2 dB/mm to 14 dB/mm. © 2004 Wiley Periodicals, Inc. Microwave Opt Technol Lett 40: 216–218, 2004; Published online in Wiley InterScience (www.interscience.wiley.com).
