    摘要: Attenuators used to regulate optical signals are disclosed. According to one aspect of the present invention, an assembly including an IR source and an IR sensor is provided to sense blockage of optical signals transmitted between two collimators via a fixed common light blocker that is driven by a stepper motor. The movement of the light blocker is sensed by a sensing assembly including an IR source and IR sensor. By detecting the photocurrent from the IR sensor and a feedback circuit, the attenuation of the optical signals can be well controlled.

    摘要: Designs of optical devices providing multiplexing or demultiplexing functions are disclosed. According to one embodiment, an optical device or an assembly employs an array of micro lenses, an array of filters and a mirror or an array of mirrors all bonded onto a substrate to provide multiplexing or demultiplexing functions. To compensate for possible errors caused by some or all of these components, one or more compensatory optical plates are provided to respectively correct these errors. Depending on implementation, the compensatory optical plates may be designed differently to correct various errors.

    摘要: Designs of optical devices particularly useful for separating channels signals that are originally multiplexed are disclosed. In accordance with one design, an optical filter configured to reflect a particular channel signal is positioned to receive a multiplexed signal at a small incident angle so as to minimize residuals of other signals in the channel signal. To further increase isolation from the other channel signals, another filter is introduced to transmit only the reflected channel signal, the another filter has a frequency response reciprocal to that of the original optical filter. One of the key advantages, benefits and objects of the designs is to increase channel signals separation efficiency by increasing isolation among separated channel signals.

    摘要: New designs of optical devices, particularly for adding or dropping a selected wavelength or a group of wavelengths as well as multiplexing a plurality of signals into a multiplexed signal or demultiplexing a multiplexed signal into several signals are disclosed. According to one aspect of the present invention, an isolator core is built into the optical devices to stop a reflected signal from an optical file in the optical devices. As a result, the optical devices are amenable to small footprint, broad operating wavelength range, enhanced impact performance, lower cost, and easier manufacturing process.
