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.
