摘要： A photonic integrated circuit apparatus is disclosed. The apparatus includes a photonic chip (200) and a lens array coupling element (100). The photonic chip includes a waveguide (202) at a side edge surface of the photonic chip. The lens array coupling element is mounted on a top surface of the photonic chip and on the side edge surface. The coupling element includes a lens array (102) that is configured to modify spot sizes of light traversing to or from the waveguide. The coupling element further includes an overhang (104) on a side of the coupling element that opposes the lens array and that abuts the top surface of the photonic chip. The overhang includes a vertical stop surface (1 12) that has a depth configured to horizontally align an edge of the waveguide with a focal length of the lens array and that vertically aligns focal points of the lens array with the edge of the waveguide.

摘要： A broadly tunable single-mode infrared laser source based on semiconductor lasers. The laser source has two parts: an array of closely-spaced DFB QCLs (or other semiconductor lasers) and a controller that can switch each of the individual lasers in the array on and off, set current for each of the lasers and, and control the temperature of the lasers in the array. The device can be used in portable broadband sensors to simultaneously detect a large number of compounds including chemical and biological agents. A microelectronic controller is combined with an array of individually-addressed DFB QCLs with slightly different DFB grating periods fabricated on the same broadband (or multiple wavelengths) QCL material.

摘要： Methods and apparatus for improved single-mode selection in a quantum cascade laser. In one example, a distributed feedback grating incorporates both index-coupling and loss-coupling components. The loss-coupling component facilitates selection of one mode from two possible emission modes by periodically incorporating a thin layer of "lossy" semiconductor material on top of the active region to introduce a sufficiently large loss difference between the two modes. The lossy layer is doped to a level sufficient to induce considerable free-carrier absorption losses for one of the two modes while allowing sufficient gain for the other of the two modes. In alternative implementations, the highly-doped layer may be replaced by other low-dimensional structures such as quantum wells, quantum wires, and quantum dots with significant engineered intraband absorption to selectively increase the free-carrier absorption losses for one of multiple possible modes so as to facilitate single-mode operation.
