Abstract :
An adjustable multichannel in-fibre bandpass filter is demonstrated by mechanically straining a uniform fibre grating to form a three-mirror Fabry-Perot cavity. A channel filter with a ~3.0 nm stop and a passband of 0.009 nm is achieved. Two, three, and four-channel passband filters with a free spectral range of ~0.25 nm are also demonstrated
