A passive self-alignment fiber-to-fiber optical device is provided. The device includes a silicon base, a fiber alignment region, and an actuation region. When the device is configured as a fiber optical attenuator, displacement of a plunger in the actuation region alters the alignment of two optical fibers in the fiber alignment region, thereby varying the optical intensity between the two fibers. A series of beams in the actuation region successively reduces an initial displacement of a first beam to a smaller displacement of the plunger. When the device is configured as an optical switch, displacement of the plunger in the actuation region displaces the first optical fiber from a first position in alignment with the second optical fiber into a second position in alignment with a third optical fiber.

A microelectrical mechanical system (MEMS) implementation of tunable Fabry Perot filter devices is disclosed. The advantages associated with the use of these tunable etalons include increases in aperture size, displacement, reliability, and a reduction in cost. In some examples, integrated tunable detectors in miniature spectrometers using a thermal driven MEMS Fabry-Perot tunable filter are provided. Other examples use integrated thermal driven tunable MEMS Fabry-Perot filter to select fiber optical communication channel.

A method is disclosed to provide improved fiber inline optical power monitoring that eliminates the need for micro-bending the fiber or for fabricating micro-reflector on the fiber. A subset of light is tapped through an offset at a fusion-spliced upstream and downstream optic fiber, and is guided out of the downstream fiber by a light guide to a reflector and photo-sensing measurement. The disclosed inline fiber monitoring is thus cost effective, wavelength independence, reliable, stable, and also causes less light transmission loss.
