摘要： This invention relates generally to custom optical filters such as filters relating to, flat-top WDM multiplexer/demultiplexers, flat-top and peaky comb filters or reconfigurable add & drop filters. The embodiment disclosed below is based on mid-dispersion wavelength bands processing, wherein the optical spectrum is dispersed in two steps; in-between these two steps, the wavelength bands are manipulated in the focal plane, for example by being moved, reflected, absorbed, inverted, magnified or reduced to achieve a particular result. A masked mirror or masked transmissive element selects wavelength by position. The mask shape for relatively complex filtering functions is much simpler than currently used for collimated beams because of the correlation between position and wavelength. Inversion of channel bands or movement of channel bands in two dimensions in the focal plane, in particular, enables the construction of numerous useful devices. It is possible to realize custom flat-top optical filters, custom shaped optical filters, flat-top WDM multiplexer/demultiplexers, flat-top and peaky comb filters or reconfigurable add & drop filters.
摘要翻译：本发明一般涉及定制光学滤波器，例如与平顶WDM多路复用器/解复用器，平顶和峰值梳状滤波器或可重新配置的分插滤波器有关的滤波器。下面公开的实施例基于中间色散波长带处理，其中光谱分散在两个步骤中; 在这两个步骤之间，波长带在焦平面中被操纵，例如通过被移动，反射，吸收，反转，放大或缩小以获得特定的结果。屏蔽镜或屏蔽透射元件按位置选择波长。由于位置和波长之间的相关性，用于相对复杂滤波函数的掩模形状比目前用于准直波束的掩模形状简单得多。特别地，在焦平面中的通道带的反转或通道带的移动在二维中能够构建许多有用的装置。可以实现定制的平顶光学滤波器，定制形状的滤光器，平顶WDM多路复用器/解复用器，平顶和峰值梳状滤波器或可重配置的分插滤波器。

摘要： A number of variations are provided of a device that provides an amplified single polarization optical signal. Each of these relies on the use of a non-polarization maintaining gain medium through which the signal is directed, and a polarization shifter and reflector that direct the signal back through the same gain medium with a shifted polarization state. An input polarization beamsplitter directs the returning optical signal away to an output, based on its shifted polarization state. The embodiments of the invention include the use of double-clad fiber. Multiple stages may be used to provide specific amplification parameters. In one embodiment, both amplification stages reside in the same polarization shifting optical path. A polarization maintaining amplifier of this type may be used as part of a master oscillator-power amplifier, in which polarization maintaining fiber is used as part of the source laser. Wavelength selective components are also used in certain embodiments of the invention, to allow for wavelength selectivity, as well as a single polarization state, in amplifiers, lasers and amplified spontaneous emission (ASE). In one embodiment, an optical circulator is used to allow the amplified, shifted polarization state signals to be directed away from the input to a desired output port. A feedback loop may also be used to control the polarization state at the amplifier output. A polarization beamsplitter at the output directs light not having the desired polarization state to a photodetector, the output of which is used by a polarization controller at the input, such that the input polarization state is adjusted until the control signal from the photodetector is minimized.

摘要： A method for in situ synthesis of graphene along a lengthwise direction of a waveguide applied to a photonic device includes processing an evanescent field of laser propagating in the waveguide to spread outward the waveguide, depositing a nickel thin film on a surface of the waveguide, growing graphene between a surface of the waveguide and a nickel thin film by irradiating telecommunication laser to a core of the waveguide, and removing the nickel thin film from the waveguide. Accordingly, graphene with high optical nonlinearity is in situ synthesized in the photonic device.

摘要： A lidar system with a pulsed laser diode to produce a plurality of optical seed pulses of light at one or more operating wavelengths between approximately 1400 nm and approximately 1600 nm. The lidar system may also include one or more optical amplifiers to amplify the optical seed pulses to produce a plurality of output optical pulses. Each optical amplifier may produce an amount of amplified spontaneous emission (ASE), and the output optical pulses may have characteristics comprising: a pulse repetition frequency of less than or equal to 100 MHz; a pulse duration of less than or equal to 20 nanoseconds; and a duty cycle of less than or equal to 1%. The lidar system may also include one or more optical filters to attenuate the ASE and a receiver to detect at least a portion of the output optical pulses scattered by a target located a distance.

摘要： A lidar system with a light source to emit a pulse of light and a receiver to detect a return pulse of light. The receiver can include a first channel to receive a first portion of the return pulse and produce a first digital output signal, and a second channel to receive a second portion of the return pulse and produce a second digital output signal. The receiver can include a logic circuit to produce an output electrical-edge signal in response to receiving the digital output signals. The receiver can also include a time-to-digital converter to determine a time interval based on an emission time of the pulse of light and based on the electrical-edge signal. The lidar system can also include a processor to determine a distance to a target based at least in part on the time interval.

摘要： A hybrid external cavity multi-wavelength laser using a QD RSOA and a silicon photonics chip is demonstrated. Four lasing modes at 2 nm spacing and less than 3 dB power non-uniformity were observed, with over 20 mW of total output power. Each lasing peak can be successfully modulated at 10 Gb/s. At 10−9 BER, the receiver power penalty is less than 2.6 dB compared to a conventional commercial laser. An expected application is the provision of a comb laser source for WDM transmission in optical interconnection systems.
