摘要	The present invention is directed to the integration of a quantum cascade laser with a hollow waveguide on a chip to improve both the beam pattern and manufacturability. By coupling the QCL output into a single-mode rectangular waveguide the radiation mode structure can be known and the propagation, manipulation, and broadcast of the QCL radiation can then be entirely controlled by well-established rectangular waveguide techniques. By controlling the impedance of the interface, enhanced functions, such as creating amplifiers, efficient coupling to external cavities, and increasing power output from metal-metal THz QCLs, are also enabled.
其他摘要	本发明涉及在芯片上集成具有中空波导的量子级联激光器，以改善光束图案和可制造性。通过将QCL输出耦合到单模矩形波导中，可以知道辐射模式结构，然后可以通过完善的矩形波导技术完全控制QCL辐射的传播，操纵和广播。通过控制接口的阻抗，还实现增强的功能，例如产生放大器，与外部空腔的有效耦合，以及增加来自金属 - 金属THz QCL的功率输出。
主权项	An integrated quantum cascade laser and rectangular waveguide device, comprising: a substrate; a metallic hollow waveguide on the substrate; a quantum cascade laser, comprising a metal-metal waveguided heterostructure active region for generation of laser light, on the substrate; and an interface between an end facet of the quantum cascade laser and an entrance end of the hollow waveguide for coupling of the laser light from the quantum cascade laser into the hollow waveguide or for coupling external light from the hollow waveguide into the quantum cascade laser.
