Miniaturization of optical components could give way to dense photonic-integrated circuits. Here, the authors demonstrate the control of evanescent waves using all-dielectric metamaterials and show that they can reduce cross-talk and bending loss, wh

The quick, reliable, and sensitive detection of bacterial contamination is desired in areas such as counter bioterrorism, medicine, and food/water safety as pathogens such as E. coli can cause harmful effects with the presence of just a few cells. Ho

Ultra-compact, densely integrated optical components manufactured on a CMOS-foundry platform are highly desirable for optical information processing and electronic-photonic co-integration. However, the large spatial extent of evanescent waves arising

An optical diode transmits forward 10Gbps data with less than 0.5dB power penalty, while suppressing and distorting backward data with a 11dB nominal power penalty. The nonreciprocal transmission is also demonstrated with a silicon modulator.

We investigate the direct butt coupling between slot and strip waveguides. Contrary to popular belief, the apparent mode mismatch does not deteriorate conversion efficiency. The direct coupler shows 95% conversion efficiency with a broad bandwidth.

Strong confinement of light in silicon waveguides allows for sharp bends and, as a result, high-density integration. However, the mode transition loss between the straight and bent portions of a silicon waveguide begins to affect the device performan

Microcavity structures have recently found utility in chemical/biological sensing applications. The appeal of these structures over other refractive index-based sensing schemes, such as those based on surface plasmon resonance, lies in their potentia

The polarization compositions of fundamental quasi-TE and quasi-TM modes of a strip silicon waveguide are characterized with free-space polarizers, and their polarization extinction ratios depend on the sizes of various apertures in the experimental

An add-drop filter with asymmetric coupling to bus waveguides, cascaded with a notch filter, achieves diode and transistor effects, and realizes NAND and NOR logic without physically altering the device, emulating the function of neurons.

We demonstrate 40 dB nonreciprocal transmission at telecommunication wavelengths using an integrated all silicon optical diode. The nonreciprocal transmission ratio is the highest to date for CMOS compatible silicon integrated photonics.
