摘要：

A new inline optical filter is reported. A GaAs/AlGaAs multilayer interference filter was lifted off its GaAs substrate by selective etching, and was sandwiched between two gradient-index rod lenses. Near-theoretical performance was obtained, with over 20 dB rejection in the stop band and less than 0.5 dB insertion loss at transmission peaks. This type of filter could be extremely useful in wavelength division multiplexed systems.
