摘要： Various designs of pluggable variable optical attenuator (VOA) are disclosed. A pluggable VOA has an optical fiber adaptor connected to an internal VOA via different fiber optical interface configurations. At least a pair of ports is provided to accept optical fibers or external optical fiber ferrules for optical pluggability. The VOA is controlled electronically or manually. To facilitate a control of the VOA via a hosting system, an electronic device and/or interface is provided. External commands take the control of the VOA and set an attenuation level within a specification when the pluggable variable optical attenuator device is connected to a hosting system.

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： Techniques for designing optical devices with high reflection isolation are disclosed. According to one aspect of the devices, an optical filter and a reflecting element are used. Depending on implementation, the reflecting element may be another optical filter, a prism and a mirror. The reflecting element is provided to direct a reflected light beam from the optical filter back to the optical filter for additional filtering, wherein the reflected light is a filtered signal that is presumably carrying residuals of unwanted signals (e.g., a transmitted signal of the optical filter). With a proper placement of the reflecting element with respect to the optical filter, the reflected light beam can be redirected back to the optical filter for a predefined number of times so that the errors or residuals in the reflected light beam are much reduced, if not completely removed.

摘要： Techniques for designing optical devices that can be manufactured in volume are disclosed. An optical assembly is build individually and includes a first tube with one end being polished to a slanted angle and attached with a filter. Because of the slanted angle, a predefined angle of incidence can be defined. The assembly is then bonded to a substrate on which other components or more such assemblies are bonded to form an integrated piece. Depending on implementation, the first tube may include no other element, a lens, or a lens and a fiber pigtail that are encapsulated. In the case that the first tube includes no other element or only a lens, a second tube is provided to include a fiber pigtail and a lens, or simply a fiber pigtail. One of the advantages of having two tubes is the underlying mechanism providing a lateral adjustment between the two tubes.

摘要： Techniques for designing optical devices with high isolation are disclosed. The high isolation is achieved by causing a reflected light signal to go through another filter. According to one embodiment, an optical apparatus comprises a first optical filter configured to transmit a first selected wavelength and reflect all other wavelengths, a second optical filter the second optical filter configured to transmit a second selected wavelength and reflect all other wavelengths. The first optical filter, being not perfect and producing a reflected signal with a residual of a signal at the first selected wavelength, the residual of the signal is minimized by the second optical filter when the reflected signal is impinged upon the second optical filter.
