Abstract
According to one embodiment, the present application includes a tunable laser configured in a small package. The tunable laser includes a housing with a volume formed by exterior walls. An electrical input interface is positioned at the first end of the housing and configured to receive an information-containing electrical signal. An optical output interface is positioned at the second end of the housing and configured to transmit a continuous wave optical beam. A tunable semiconductor laser is positioned in the interior space and operable to emit a laser beam having a selectable wavelength. A focusing lens assembly is positioned in the interior space along an optical path of the laser beam to operatively couple the laser beam to the optical output interface.
Claims15
A small, packaged tunable laser comprising:
- a rectangular housing having a volume of less than 0.6 cubic centimeters, with six planar exterior walls including a bottom, a top, opposing first and second ends, and opposing sidewalls, the exterior walls forming a hermetically sealed interior space that includes a major axis that extends through the first and second ends;
- an electrical input interface positioned on the exterior of the housing and configured to receive an information-containing electrical signal;
- an optical output interface positioned at the second end of the housing and aligned with the major axis, the optical output interface configured to transmit a continuous wave optical beam;
- a tunable semiconductor laser positioned in the interior space and operable to emit a laser beam having a selectable wavelength;
- and
- a focusing lens assembly positioned in the interior space along an optical path of the laser beam to operatively couple the laser beam to the optical output interface.
A small, packaged tunable laser comprising:
- a rectangular housing with six planar sides including a bottom, top, first end, second end, and two opposing sidewalls, the housing including a hermetically sealed interior space with a length measured between the first and second ends and a width measured between the opposing sidewalls, the length being larger than the width;
- laser components positioned in the interior space and including coupling optics and an external cavity laser with a tunable filter, the laser components aligned within the interior space with an optical path of a laser beam that emanates at the external cavity laser and extends along the coupling optics substantially perpendicular to the first and second ends and along a portion of the length of the housing;
- an electrical input interface positioned at the first end of the housing and configured to receive an information-containing electrical signal;
- and
- an optical output interface positioned at the second end of the housing and configured to transmit a continuous wave optical signal.
