    摘要: An optical interface between an optical fiber and a laser is provided. The optical fiber has a core and an end. The optical interface includes a mirror that is capable of receiving an optical output of the laser and of reflecting the optical output to the end of the optical fiber such that a chief ray of the optical output is incident on the core of the optical fiber. The optical interface also includes a lens located such that the chief ray of the optical output traverses a center of the lens. Such optical interface may be used in a transmitter optical subassembly (TOSA) having a vertical TO package for un-cooled lasers.

    摘要: An optical interface between an optical fiber and a photodiode is provided. The optical fiber has an end. The optical interface includes a lens located such that a chief ray of an optical signal outputted at said end traverses a center of the lens. The lens may be a ball lens or a lens having an orientation such that the chief ray is incident substantially normal to a center of the lens.

    摘要: A laser transmitter that includes a heating element coupled to the laser package and controlled to allow the laser to be kept at a higher temperature than ambient when low temperature extremes occur, thus limiting the range of wavelengths output by the laser over a given temperature range. The laser transmitter includes a semiconductor laser having an associated operating temperature; a laser driver circuit coupled to the semiconductor laser to control a modulation current and bias current conducted by the semiconductor laser; a heating element thermally coupled to the semiconductor laser; and a heating control circuit that (i) senses a temperature substantially representative of the ambient temperature surrounding the laser transmitter, (ii) energizes the heating element to provide heat to the semiconductor laser only when the temperature substantially representative of the ambient temperature is sensed below a predetermined minimum temperature, and (iii) upon energizing the heating element, controls heating of the heating element based on the temperature substantially representative of the ambient temperature.
