We report on microring resonator with integrated photonic crystal that is capable of supporting discrete Raman signals with 7 orders of magnitude enhancement in the spectral range of 2–5 pm. The proposed platform can be used for advanced spectroscopic sensing applications.

Superior performance of digital alloy APDs is attributed to the formation of "minigaps" in the material band-structure. However, no improvement is observed in dilute nitride APDs in presence of minigaps. We propose criteria which can judge the effectiveness of these minigaps.

In this paper, we experimentally study broadband perfect absorber based upon tungsten boride. We show that the absorptance of the WB perfect absorber has much better temperature stability when compared with an Al based absorber: its absorptance changes little from 25° C to 270° C.

We demonstrate a tunable multimode interference filter, assembled with chalcogenide fibers. This filter has an insertion loss of 1.46 dB, a FWHM bandwidth of 26 nm, and a wavelength tunability of 84 nm from 1926 nm to 2010 nm.

Light guiding is an essential functionality of automotive lighting responsible for styling, safety and artistic effects. The proposed light guide is characterized by a wedged design with a sine-shaped light-redirecting surface. In this study, a new microfabrication method called laser structuring-by-remelting was used to fabricate tooling for wedged light guides. Their preliminary characterization includes the assessment of the shape accuracy, surface quality as well as optical performance as assessed through both simulation and experimental techniques.

A micro-LED-coupled multimode slab waveguide is reported for fluorescence sensing. The device consists of a 1-dimensional micro-LED array coupled to a sub-mm polymeric slab for evanescent excitation of fluorescent analytes present on the surface. Proof-principle detection of semiconductor nanocrystals down to 0.2 pM/cm2 is demonstrated.

Co-integrated neuromorphic photonic and electronic processors promise orders of magnitude improvements in both speed and energy efficiency over purely digital electronic approaches. We discuss neuromorphic photonic systems and their application to deep convolutional neural networks inference.

Methylene Blue (MB), an FDA approved dye, has been widely used in clinical applications. However, issues remain for its use as contrast agent: production of 1O2, reduction into leuco-MB, and nonspecific tagging. These issues were addressed by loading MB into Poly-Lactic-co-Glycolic Acid (PLGA) particles.
