摘要： The present invention provides an optical multimeter (100) for use in calibrating and testing optical components. The optical multimeter (100) includes an analog/digital signal generator (250) for delivering an output beam (260) over a wide range of frequencies, duty cycles and amplitudes. Circuitry is also provided for modulation (222) of an analog signal onto the output. The signal generator (250) includes a tunable laser that is thermally stabilized as to optical path length, as well as tuning angle of the tuning element. The tunable laser exhibits a small form factor due in part to a novel wavelength control process which utilizes an open loop system to maintain precise output wavelength (260) control without the requirement of either a wavelength or position feedback device. Additionally, the tunable laser incorporates an inexpensive modulator circuit (222) which combines a low frequency closed loop power control with a separate digital modulator.

摘要： Disclosed are both a housing and an assembly for a tunable external cavity laser. The housing includes: a base section (302), a motion section (306), and an actuator (366). The base section includes a proximal and distal portion, and the laser (324) and the dispersive element (602, attached to mounting surface 328) mounted at respectively the proximal and distal portions such that energy emanating from the laser strikes the dispersive element leaving the dispersive element as a second beam at an angle with respect to the first beam which depends on wavelength. The motion section includes a proximal and a distal portion and a torsional member (362 A-B) positioned at the proximal portion and the reflector (364) positioned at the distal portion to reflect the second beam to the laser via the dispersive element, and the motion section supported by the base about the torsional member. The actuator (366) is in selectively engageable abutment against the distal portion of the motion section to move the reflector with respect to the dispersive element about the torsional member to tune the external cavity laser.

摘要： A precision component mounting and positioning apparatus (10) comprises a frame member (12) and a stage member (14) suspended in the frame member (12). The frame member (12) is adapted to be mounted on a support surface, and the stage member is adapted to receive a precision component, typically a precision optical component such as an optical fiber or waveguide. The stage member (14) can be positionally adjusted relative to the frame member (12) in five degrees of freedom. Three axially oriented actuators (20) are grounded in the frame member (12) to provide for selectively rotating the stage member (14) about two orthogonally disposed transverse axes relative to the frame member as well as for axially translating the stage member (14) relative to the frame member (12). A pair of orthogonally opposed transverse actuators (22) are grounded in the frame member (12) and oriented to provide for transverse translation of the stage member (14) relative to the frame member (12).
