    摘要: A compact sensor for detecting the presence of biological or chemical species includes a microdisk laser and a wavelength shift detector. The microdisk laser is coated with a biological or chemical recognition element, which binds preferentially with a target analyte. Because the recognition element and the target analyte adhere to the sidewall surface of the microdisk laser, they increase the effective diameter of the laser, which shifts the output wavelength by a detectable amount. The presence of a wavelength shift indicates the presence of the target analyte, and the magnitude of the wavelength shift corresponds to the mass load of the target analyte on the sidewall surface of the microdisk laser.

    摘要: An improved method of analyzing target analytes in a sample is described. The method is based on anti-resonant guided optical waveguides which enables a strongly improved light-target interaction since the light can be guided within the target-containing medium. The light-target interaction can be monitored by many different means to determine characteristics of the target analyte. The anti-resonant waveguide concept is suitable for a large variety of characterization methods and combinations of them, since it is relatively unaffected by changes to both wavelength and film thickness.

    摘要: A method and structure for adjusting the wavelength output of a semiconductor device is described. In the method, the hydrogen concentration in an active region of the semiconductor device is adjusted either during fabrication or after the device has been fabricated. The adjustment provides a simple technique for fine tuning many device types including regular lasers and VCSEL structures. The adjustment also allows for mass production of lasers of many different frequencies on a single wafer substrate, a system particularly desirable for wavelength division multiplexing systems.
