Abstract: A method and an apparatus for determining a photographing delay time and a photographing device are disclosed. The method includes: controlling the photographing device to form, according to a preset imaging cycle, an image of a photographed object, and storing an imaged photo; each time photographing is initiated, displaying the imaged photo and receiving a first operation instruction entered by a user; determining, according to the first operation instruction, a corresponding target imaged photo; calculating a difference between an initiation moment of each time of photographing and an imaging moment of the corresponding target imaged photo, to obtain a delay time corresponding to a single time of photographing; and calculating an average value of delay times corresponding to at least two times of photographing, where the average value may be used as a standard delay time caused by an operation of the user on the photographing device.

Abstract: Embodiments of the present invention disclose an optical transmitter and an optical transmission method. An embodiment of the present invention includes a directly modulated laser array and a micro-ring group array, where the directly modulated laser array may output multiple channels of optical signals, each directly modulated laser is correspondingly provided with one circular waveguide group and one first waveguide, each circular waveguide group may couple a part of optical signals output by a directly modulated laser corresponding to the circular waveguide group to a same second waveguide, and the second waveguide aggregates optical signals from circular waveguide groups and outputs an aggregated optical signals. The micro-ring group array implements not only filtering but also multiplexing, which effectively reduces a quantity of elements, reduces a size of an optical transmitter, and reduces costs.

Abstract: A laser includes a substrate and a resonant cavity. In addition to an active gain region, a first phase shift region, an optical branching region, and N reflective mode selection regions, the resonant cavity further includes a highly reflective surface, where a reflectivity of the highly reflective surface is greater than reflectivities of the N reflective mode selection regions, so that laser beams are output from the N reflective mode selection regions. Because the laser naturally includes at least two reflective mode selection regions, at least two laser beams are output. According to the laser provided by the embodiments of the present invention, one laser can output two laser beams or even multiple laser beams; therefore, laser beam generation efficiency is high and average costs for generating a single laser beam are accordingly reduced.
Abstract translation: 激光器包括衬底和谐振腔。 除了有源增益区域，第一相移区域，光分支区域和N反射模式选择区域之外，谐振腔还包括高反射表面，其中高反射表面的反射率大于 N反射模式选择区域，使得从N个反射模式选择区域输出激光束。 因为激光器自然地包括至少两个反射模式选择区域，所以输出至少两个激光束。 根据本发明实施例提供的激光器，一个激光器可以输出两束激光束，甚至多个激光束; 因此，激光束产生效率高，并且相应地减小了用于产生单个激光束的平均成本。
