Abstract

We report a novel FSK modulation/single-filter detection system which does not require an intermediate-frequency locking loop. Instead, this system utilizes laser frequency-locked to an atomic line (krypton 2p8-3d1” transition at 1.5224 µm) as both transmitter and local oscillator. As a result, communication can be initiated without any manual adjustment to match the wavelengths of transmitter and local oscillator lasers.
