Paper Abstract
Narrow band-pass optical interference filters are used for a variety of applications to improve signal
quality in laser based systems. Applications include LIDAR, sensor processing and free space
communications. A narrow band width optical filter allows for passage of the laser signal while rejecting
ambient light. The more narrow the bandwidth, the better the signal to noise. However, the bandwidth
of a design for a particular application is typically limited by a number of factors including spectral shift
over the operational angles of incidence, thermal shift over the range of operating temperature and, in
the case of laser communication, rejection of adjacent laser channels. The trade-off of these parameters
can significantly impact system design and performance. This paper presents design and material
approaches to maximize the performance of narrow bandpass filters in the infrared.
