Cooled Laser Module

An optoelectronic device comprising:

• a header having a plurality of pins extending therethrough;
• a light emitting device operable to emit an optical signal in response to an electric signal received by at least one of the plurality of pins, said light emitting device being operable to emit light from two opposing sides;
• a light detector;
• and
• a cap substantially enclosing the light emitting device and the light detector, the cap having a window operable to transmit light emitted from one of said two opposing sides of the light emitting device,
• wherein light emitted from the other of said two opposing sides of the light emitting device is emitted along a light path directly to the light detector, and
• wherein the light detector is positioned perpendicular to a central axis of the light path for light emitted from said other of said two opposing sides away from said central axis of the light path.

An optoelectronic device comprising:

• a header having a plurality of pins extending therethrough;
• a light emitting device mounted on the header, the light emitting device operable to emit an optical signal in response to an electric signal received by at least one of the plurality of pins;
• a lens operable to receive at least some of the light emitted by the light emitting device;
• a thermo-electric cooling device mounted adjacent to a side of the header;
• and
• a cap substantially enclosing the thermo-electric device, the light emitting device and the lens, the cap having a window operable to transmit light emitted by the light emitting device which has passed though the lens,
• wherein the lens is the only optical component in said light path between the light emitting device and the window.
