Paper Abstract

The recent availability of ultra-fast laser diodes with matching fast photodetectors that can be directly modulated at radio frequencies (RF) offer an alternative interconnection technology in airborne systems. If these devices are used with optical fibers they can replace RF cables, because they can save substantially on weight and cost while providing superb Electromagnetic Interference (EMI), Electromagnetic Pulse (EMP), and TEMPEST performance. Preliminary measurements of the RF/microwave response of laser diodes and matching detector will be reported. The measurements include insertion loss, dynamic range, bandwidth, single tone harmonic generation, and two tone intermodulation products. Discussion of results will address the sensitivity of the laser diode/detector to modulation index and frequency. The optical subsystem will be examined over the frequency range 100 MHz to 10 GHz. A candidate Satellite Communication (SATCOM) terminal design will be discussed that uses the fiber optics to interconnect subsystems. Recommendations for combining RF and digital signals using RF and color multiplexing will be reported.
