Abstract:
A pin hole or aperture is located or formed adjacent to the end surface of one or more of the input ports or fibers, or adjacent to one or more of the output ports or fibers, of a fiberoptic component. The aperture allows light to enter (or exit) the core of the associated fiber, and the non-transparent layer that surrounds the aperture blocks light from entering or exiting the cladding layer of the associated fiber. This blocking of the evanescent field in the cladding layer serves to reduce the polarization, wavelength, and temperature dependencies of the light coupling to the output port(s) or fiber(s) of the optical component. It can also reduce the passband width of the selected wavelength in tunable optical filter applications. The non-transparent layer surrounding the aperture can be made reflective, and light that is reflected by the non-transparent layer can be used for optical power monitoring.

Claim (Index 1):
An optical component, comprising:\n a first optical fiber terminating in a first end and having an inner core radially surrounded by an outer cladding, the inner core having a higher index of refraction than an index of refraction of the outer cladding; a second optical fiber terminating in a second end and having an inner core radially surrounded by an outer cladding, the inner core having a higher index of refraction than an index of refraction of the outer cladding, the second end of the second optical fiber proximate to the first end of the first optical fiber; and a reflective end structure covering the first end of the first optical fiber and having a transparent aperture, the first and second optical fibers aligned such that light transmitted from the inner core of the second end of the second optical fiber and incident on the reflective end structure is transmitted through the transparent aperture to the inner core of the first end of the first optical fiber, and the first and second optical fibers are further aligned such that at least a portion of light transmitted from the second end of the second optical fiber that is incident upon the reflective end structure is reflected back toward the second end of the second optical fiber, and the optical component is configured to monitor the light reflected toward the second end of the second optical fiber and propagated back through the second optical fiber.
