摘要： Techniques for micro-optics alignment and assembly are described. By attaching a needle pin to an optical component to be assembled, the optical component can be placed and aligned within a limited space. After the aligned optical component is permanently bonded to a substrate or to another component, the needle pin is detached from the component. This technique allows a user to place and align a small optical component to a right position.

摘要： Disclosed herein is a wavelength-division multiplexing device with a unified passband. In particular, disclosed is a wavelength-division multiplexing (WDM) device with at least a common port, a channel port, and a WDM filter. The common port is configured for optical communication of a multiplexed signal to the WDM filter. A demultiplexed signal of the multiplexed signal includes a first secondary demultiplexed signal within a first wavelength range and a second secondary demultiplexed signal within a second wavelength range, which are separated from each other by a third wavelength range. The first WDM filter has a single unified passband including the first wavelength range, the second wavelength range, and the third wavelength range, such that the first WDM filter is configured to pass the first secondary demultiplexed signal and the second secondary demultiplexed signal to the first channel port.

摘要： An optical signal isolation device comprising a common port, an isolated diagnostic port, an integrated circulator comprising an input circulator fiber, an output circulator fiber, and a fiber-to-fiber optical coupler configured to couple an isolated optical signal propagating along the input circulator fiber to the output circulator fiber for propagation along the output circulator fiber, a multi-fiber alignment body that secures at least portions of each of the multi-signal fiber, the isolated diagnostic signal fiber, the input circulator fiber, and the output circulator fiber, and a wavelength-selective optical assembly including an optical signal filter, fiber-to-filter focusing optics, and a communications signal reflector. The integrated circulator and the wavelength selective optical assembly are configured such that the communications component is retro-reflected back to the common port and the diagnostic component is passes out of the isolated diagnostic port.

摘要： A variable optical attenuator is provided. The variable optical attenuator includes an input optical fiber, an output optical fiber, a non-attenuating, transmission-type diffracting prism and a prism positioning system. The input optical fiber, the non-attenuating, transmission-type diffracting prism and the output optical fiber are optically arranged such that an optical path from the input core of the input optical fiber to the output core of the output optical fiber passes through the non-attenuating, transmission-type diffracting prism. The non-attenuating, transmission-type diffracting prism diffracts an optical signal propagating from the input optical fiber to the output optical fiber such that an input portion of the optical path is non-linear with an output portion of the optical path. The prism positioning system changes a pose of the non-attenuating, transmission-type diffracting prism within the optical path thereby attenuating the optical signal.

摘要： Filters shaped differently from those commonly used in WDM Mux/DeMux optical devices are described. Different from the prior art devices that commonly use filters shaped in cuboid, the filters in the embodiment of the present invention are shaped in parallelepiped. In other words, a cross section of such filter is not in parallelogram. According to one embodiment of the present invention, a filter is so cut that a cross section thereof presents a cutting angle not being 90 degrees. As a result, the filter is fully used in WDM Mux/DeMux optical devices. Such filters are advantageously used in compact optical modules.
