Abstract
An optical transmission apparatus having a temperature control function includes: a package having a cavity; a cooler mounted in the cavity and controlling temperature; and a substrate mounted on the cooler and including a light source mounted thereon to generate light. In spite of the presence of the cooler, the apparatus can be implemented to be compact and have a simple structure.
Claims6
An optical transmission apparatus comprising:
- a base having a cavity disposed in an upper part of the base, the cavity being recessed from a top surface of the base;
- a cooler configured to control a temperature of the optical transmission apparatus, the cooler mounted on a bottom surface of the cavity disposed in the upper part of the base;
- a substrate mounted on the cooler;
- a light source mounted on the substrate and configured to generate light,
- a support mounted on the cooler;
- a monitoring light reception element mounted on the support and receiving light to perform a monitoring operation;
- and
- a reflector mounted on the cooler and totally reflecting light from the light source to an outside,
- wherein the reflector comprises:
- a bar mirror having a sloped face formed on an area to which light is made incident;
- and
- a total reflection coated film formed on the sloped face, and
- wherein the support and the reflector are each mounted directly on a same surface of the cooler.

An optical transmission apparatus comprising:
- a package having a cavity;
- a cooler mounted in the cavity and controlling a temperature;
- a substrate mounted on the cooler and including a light source mounted thereon to generate light;
- a reflector mounted on the cooler such that it is positioned in front of the light source, and reflecting a majority of light from the light source to an outside and allowing a remaining portion to be transmitted therethrough, the reflector comprising:
- a bar mirror having a sloped face formed on an area to which light is made incident;
- a beam splitter coated film formed on the sloped face;
- a total reflection coated film formed on an area from which light is output;
- and
- a non-reflection coated film formed on an area that light, which has been reflected by the total reflection coated film, reaches;
- and
- a monitoring light reception element mounted on the non-reflection coated film of the reflector and performing a monitoring operation upon receiving light made incident through the reflector.
