摘要： A micromechanical optical modulator includes an input optical waveguide that projects a beam across a gap to an output optical waveguide. A phase shifting gate is mounted between the input and output optical waveguides and has a light transmissive panel which may have at least two sections of different thicknesses. The phase shifting gate is translatable between a position in which the beam of light is transmitted and a second position in which a section of the gate panel is interposed in the beam path and the beam of light is reflected by interference effects. A micromechanical actuator may be connected to the phase shifting gate to switch it between its positions. The optical waveguides may be mounted at an angle to the surfaces of the sections of the gate such that when the beam is reflected from the gate it is directed to a second output optical waveguide, which receives the beam and directs it on a new path, thereby allowing switching of optical beam paths in an optical communication system. The optical modulator may also be used as a sensor to detect effects which displace the phase shifting gate, such as in an accelerometer in which a mass is connected to the gate to move the gate when the mass is subjected to accelerations.

摘要： A method of Raman detection for a portable, integrated spectrometer instrument includes directing Raman scattered photons by a sample to an avalanche photodiode (APD), the APD configured to generate an output signal responsive to the intensity of the Raman scattered photons incident thereon. The output signal of the APD is amplified and passed through a discriminator so as to reject at least one or more of amplifier noise and dark noise. A number of discrete output pulses within a set operational range of the discriminator is counted so as to determine a number of photons detected by the APD.

摘要： A latching mechanism for a MEMS actuator as, for example, a mirror in an N×N fiber optic switch, maintains a thermally actuated mirror in its actuated position even in the event of a power interruption by a pair of clamps, which clamp against an actuator arm. Such actuator arm is thermally actuated by a bent beam type of thermal actuator. To provide for effective fabrication using the MEMS technique (microelectromechanical system), on for example, a silicon substrate where the entire moveable structure is a suspended mechanism, the clamps are fabricated in a normally closed position. In this position they typically interfere with the line of motion of an enlarged portion of an actuator arm being directly in the line of motion or with a post and slot technique.

摘要： An integrated two-dimensional tunable filter array for a matrix of fiber-optic input-output light channels includes a tunable filter chip array sandwiched between a first semiconductive wafer in which the guiding grooves for the input light channels terminate in a 45° reflecting surface causing a 90° turn of the light beams into each tunable filter of the array. Then a third semiconductive substrate is bonded to the other side of the tunable filter array to receive the reflected light beams. A 45° mirror on a {111} plane may be formed by slow etching of a {100} type wafer or the use of a {100} type wafer with a 9.7° off axis cut.
