摘要： New designs of optical devices, particularly for multiplexing or demultiplexing as well as adding or dropping are disclosed. According to one aspect of the designs, one or more beam redirecting parts (e.g., prisms or mirrors) are used in an optical device to redirect a beam for at least two purposes: to increase a distance between two optical parts that are not positioned along an optical path, by using one or two of such beam redirecting parts, and to minimize an angle of incidence (AOI) to an optical filter or to adjust the AOI to an optimum value. As a result, devices employing the techniques provide small AOL and flexibility in adjustment and are amenable to small footprint, broad operating wavelength range, enhanced impact performance, lower cost, and easier manufacturing process.

摘要： Designs of multiplexing/demultiplexing modules configured for N channels are disclosed. One of the features in the designs is to provide at least one concave mirror for compenstating filter tilting errors. The concave mirrors is placed where an incident traveling distance of a light beam is substantially similar or equal to the reflected traveling distance of the beam such that the filter tilting errors successively introduced over a number of optical filters can be successively reduced, compensated or removed over a subsequent number of optical filters as the light beams travels.

摘要： Techniques for designing optical couplers are disclosed. According to one aspect of the optical couplers, different from the prior art couplers, a holding tube (a sub-assembly) for holding an optical lens (e.g., a GRIN lens) and an optical filter (e.g., a thin film filter) is formed by concatenating two single tubes, one for accommodating the optical lens and the other for accommodating the optical filter. The two tubes are not required to have an identical dimension. As a result, inherent flexibilities are provided in the holding tube, especially the optical filter often comes in different sizes. Further, when the sub-assembly is inserted in a sleeve, only either one of the two tubes is secured to the sleeve so as to reduce a risk that, during a thermal condition change, any metal and glass material expansion will not cause the sub-assembly to be under stress that would otherwise be present when both of the tubes are secured to the sleeve. To reduce stress-related optical loss of the optical couplers, an epoxy adhesive is applied onto only a portion of an optical lens and a portion of a tube.

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.
