            Abstract : 
Free-space optical filtering technologies suitable for high-sensitivity photon-counting receivers are described. Important performance metrics include low 0.5 dB insertion loss, and low noise-equivalent-bandwidths of 7.7 pm and 62 pm at 1064 nm over a large 1000 nm operational range.
