Abstract: Methods, systems, and devices are disclosed for implementing an ultra-sensitive micro-Raman spectrometer based on high confinement nanometer-scale photonic structures, which can enhance the sensitivity while maintaining an extremely compact size. In one aspect, a portable, ultra-sensitive, chip-scale system for performing sensing and identification on liquid and gaseous samples based on Raman spectroscopy is disclosed. The disclosed chip-scale system can be especially useful for biosensing including glucose sensing and monitoring (e.g., finding concentrations of glucose in complex body fluids like blood, urine, or saliva). For example, in implementations for glucose monitoring, the disclosed technology can make an impact that not only provides relief from the typical required "finger prick" for blood sampling, but also provides an easy-to-use device that diabetics and other people in need of glucose monitoring (and eventually other types of monitoring) can use.

Abstract: An integrated optofluidic system for trapping and transporting particles for analysis is provided comprising a planar substrate; a microfluidic channel; and a waveguide integrated with the channel. A microsphere particle in the integrated optofluidic system can act as a cavity, allowing light to circulate many thousands of times around the circumference of the microsphere. Optical trapping and transport is used for nanoscale positioning to excite the microsphere resonances. Sensitive measurements on molecules can be accomplished by monitoring changes in whispering gallery modes (WGMs) that propagate around the circumference of the microsphere. By using a broadband or supercontinuum light source, a microsphere can be trapped and many WGM resonances can be excited through the visible and near-infrared wavelengths simultaneously. After the resonances are measured using the waveguide transmission, the microsphere can be freed by decreasing the optical power and the process repeated with a different microsphere.

Abstract: Systems and methods are provided for ultrafast optical waveform sampling based on temporal stretching of an input signal waveform. Temporal stretching is performed using a time lens based on four-wave mixing in a nonlinear medium. The signal is passed through an input dispersive element. The dispersed signal is sent into the time lens, which comprises a chirped pump pulse and a nonlinear medium. The chirped pump pulse is combined with the signal. The four-wave mixing process occurs in the nonlinear device or medium, which results in the generation of a signal at a new optical frequency (idler). The idler is spectrally separated from the signal and pump pulse using a bandpass filter and sent into an output dispersive element. The output dispersive element is longer than the input dispersive element and the temporal stretching factor is given by the ratio between the dispersions of these two elements.
