Patent attributes
An optical transmitter and an optical module including the optical transmitter are provided. The optical transmitter may include a support substrate, a temperature control module disposed on the support substrate, a sub-mount disposed on the temperature control module, a prism disposed on the temperature control module and having a sloped surface, a light receiving element disposed on the temperature control module, a light emitting element disposed on the sub-mount, and a thermistor disposed on the sub-mount. The light receiving element may be disposed separately from the sub-mount in a first direction, and the prism may be disposed between the light receiving element and the sub-mount. Some first light emitted from the light emitting element may be reflected by the sloped surface of the prism, and some of the first light may pass through the prism and be received by the light receiving element.
