摘要： An optoelectronic transmitter is provided including a laser diode. A control circuit for driving the laser diode includes a current source which provides a DC bias current to the laser diode, and the laser diode emits an optical signal having an average power determined by the magnitude of the bias current. A voltage regulator establishes a regulated supply voltage which is input to a first reference circuit and a feedback monitor circuit. The first reference circuit establishes a first fixed reference voltage. The feedback monitor circuit includes a monitor device for measuring the optical power emitted by the laser diode, and the monitor circuit establishes a variable monitor voltage proportional to the optical power measured by the monitor device. An op-amp compares the first fixed reference voltage and the feedback monitor voltage, and the output voltage of the op-amp controls the magnitude of the bias current output by the current source. A disable switch is incorporated for selectively blocking the bias current to the laser upon receipt of a DISABLE signal. A second reference circuit is provided for developing a second derived reference voltage, and an analog switch which is also actuated by the DISABLE signal connects the second derived reference voltage to the feedback monitor circuit while the DISABLE signal is active. Otherwise, the analog switch connects the regulated supply voltage to the feedback monitor circuit at all other times.

摘要： A small format optoelectronic package or device includes a non-electrically conductive substrate partially covered by an electrically conductive can. The electrically conductive can has a transparent element affixed to an aperture of the electrically conductive can. The electrically conductive can encloses and hermetically seals an edge emitting optical diode, a reflecting mirror, a monitor diode, and conductors between the electrically conductive can and the non-electrically conductive substrate. The non-electrically conductive substrate has three through-holes formed through a thickness of the non-electrically conductive substrate. The three through-holes are filled with an electrically conductive material so as to form three electrically conductive vias. Additionally, a surface of the non-electrically conductive substrate is organized into three regions. The first and third regions have the electrically conductive plating material applied thereto.

摘要： An optoelectronic transmitter module is provided for transmitting optical data signals from a host device. The module is housed within a grounded chassis of the host device and provides a reduced effective aperture therethrough. The module components include electronic circuitry mounted within the module configured to convert electrical data signals to an optical output signal. A conductive housing encloses the electronic circuitry. The module housing includes a first connector end adapted to receive a fiber optic connector. When the module is installed within the host device chassis, the connector end engages the host chassis to form a conductive barrier around the first end of the housing. A conductive transmitting optical subassembly (TOSA) is disposed within the connector end of the housing, forming a continuous conductive barrier therewith. The TOSA includes first and second ends with a narrow passage extending therebetween. The TOSA first end holds an optical package, and the second is configured to receive a fiber optic connector ferrule.
