Thermally Tunable FBG Filter – 0.07nm Linewidth

SKU: TTFG

The TTFG series tunable optical filter integrates a fiber Bragg grating (FBG) with a thermally tunable platform, offering a filter with narrow linewidth and wide center wavelength selection. It is available in two configurations: two-port reflection, functioning as a tunable notch filter, and three-port transmission-reflection, which acts as a tunable bandpass filter with an integrated circulator. Standard FBG linewidths range from 0.07 nm to 2 nm, with custom narrower options available. We provide tailored FBG production from 350 to 2500nm, with a one-time setup fee of approximately $1800. Additionally, our circulators cover a wide wavelength range from 350 nm to 2200 nm, supporting the three port TTFG configuration for diverse optical system requirements.
