Abstract: A large diameter waveguide is provided having a diameter of at least about 0.3 millimeters, and an outer cladding with an inner core with a long period grating included therein. The long period grating either couples forward propagating cores modes to forward propagating cladding modes of one optical signal travelling in one direction in the large diameter waveguide, or couples forward propagating cladding modes to forward propagating cores modes of another optical signal travelling in another direction in the large diameter waveguide. The long period grating has an optical parameter that changes in response to an application of a compressive force on the optical waveguide. The outer cladding may also have the long period grating written therein. The long period grating has concatenated periodic or aperiodic gratings. The optical waveguide may be shaped like a dogbone structure having wider outer sections and a narrower central section inbetween. The long period grating is written in the narrower central section of the dogbone structure. The large diameter waveguide may be used in devices such as a tunable bandpass filter, connector or collimator.

Abstract: A tunable optical filter has a large diameter cane waveguide with nullside-holesnull in the cane cross-section that reduce the force required to compress the large diameter optical waveguide without overly compromising the buckling strength thereof. The large diameter optical waveguide has a cross-section of at least about 0.3 millimeters, including at least one inner core, a Bragg grating arranged therein, a cladding surrounding the inner core, and a structural configuration for providing a reduced bulk modulus of compressibility and maintaining the anti-buckling strength of the large diameter optical waveguide. The structural configuration reduces the cross-sectional area of the large diameter optical waveguide. These side holes reduce the amount of glass that needs to be compressed, but retains the large diameter.
