A modulating retro-reflector for Free-Space Optical Communication
IEEE Photonics Technology Letters, 2006Co-Authors: Stephane Junique, Daniel Ågren, Susanne Almqvist, Bertrand Noharet, Qin Wang, Jan Y. AnderssonAbstract:We present modeling of a modulating retro-reflector for Free-Space Optical Communication, composed of a reflective resonant-cavity modulator and a corner cube. Although resonant-cavity modulators are sensitive to the angle of incidence of the light beam, we show that with the right geometrical arrangement, the field of view can be more than ten-fold that of the modulator. The modeling is validated by experimental data using a corner cube and a 14 × 14 mm2 multiple quantum-well modulator.

Fabry-Perot electroabsorption modulators for high-speed Free-Space Optical Communication
IEEE Photonics Technology Letters, 2004Co-Authors: Qin Wang, Daniel Ågren, Bertrand Noharet, Stephane Junique, Jan Y. AnderssonAbstract:Retroreflective modulators are key components in Free-Space Optical Communication systems between mobile platforms and users. Wide-aperture surface-normal electroabsorption modulators based on GaAs-AlGaAs quantum wells embedded in an asymmetric Fabry-Perot cavity are designed and fabricated with a high yield process on 10-cm wafers. It is shown that the modulator yield and its speed are improved significantly by a pixellated approach in which monolithic modulators are divided into 4-64 pixels. The fabricated 1.5/spl times/1.5 cm/sup 2/ devices exhibit contrast ratios of 8 dB at a driving voltage of 8 V and a modulation frequency higher than 10 MHz, which provides low noise and fast data transmission for long distance Free-Space Optical Communication.
