Abstract
There is described a method of fabricating an optical fiber device, the method comprising: positioning longitudinal portions of a plurality of optical fibers alongside each other in a given geometrical relationship, depositing liquid coating material around the longitudinal portions of the plurality of optical fibers; and the liquid coating material setting up around the longitudinal portions of the plurality of optical fibers thereby maintaining said given geometrical relationship along the longitudinal portions.
Claims8
An optical device comprising:
- a length of optical fiber configured for propagating an optical signal;
- and
- an optical grating inscribed along a portion of the length of optical fiber, the optical grating having a random continuous distribution such that a return signal caused by said propagating has a full width at half maximum bandwidth ranging between about 0.1 THz and about 40 THz.
