Abstract
Temperature compensated Fiber Fabry Perot filters are provided. These filters display minimal wavelength drift over a wide range of temperatures. The temperature coefficients of the filters can be adjusted after construction. These FFPs are particularly useful in applications in which filter size is a constraint. The disclosed filter designs can be employed for minaturized filters which retain thermal and optical stability over a wide range of temperatures. In particular, low-loss thermally stable FFPs suitable for use in circuit board applications are provided.
