摘要:
Optical actuators are provided in a variety of formats. Optical actuators use temperature increases or light momentum to convert the impingement of light into movement. Optical actuators (16) are provided in forms such as: an optical cavity (3) that absorbs light to cause displacement of the actuator, an optical actuator micro-mirror (34) that uses light momentum to cause rotation of the mirror (34), and a bistable shell actuator that changes shape in response to the impingement of light thereon. Optical actuators may be thermally compensated and may be attached to lever systems to multiply their effective displacements.
摘要:
The disclosure relates to an optical terminator device suitable for terminating high energy optical signals. The device includes a heat sink cap having an internal surface. An optical absorbing layer is positioned on the internal surface of the heat sink cap. A scattering core having a fiber or waveguide connection is positioned within the heat sink cap such that a thermal barrier is maintained between the optical absorbing layer and the scattering core.
