We introduce a compact spectrometer based on a 1×16-multimode interference splitter partially filled with random holes. The spectral resolution for this high-bandwidth, on-chip device is found to be at least ~0.04 nm.

Programmable Photonic integrated circuits are optical chips where the flow of light is configured through electronics. This provides a flexible way to explore new photonic functions, and a lower threshold for deployment in new applications.

We investigate a waveguide-integrated plasmonic graphene photodetector operating based on the hot carrier either photo-thermoelectric or photo-bolometric effect, which is characterized simultaneously by high responsivity on the scale of hundreds of A/W and high speed on the scale of 100’s of GHz. The proposed detector configuration is based on a hybrid waveguide that allows for efficient absorption in graphene over a short distance and subsequently a large change of conductivity. The results demonstrate the potential of graphene for high-speed communication systems.

We present a multidimensional quantum communication scheme that enables the sharing of information on the basis “non-classically”, encoding it in the same photonic qudits used for carrying the data in the quantum channel.

Photoexcited carrier relaxation dynamics were investigated using AC photoconductivity in type-II quantum wells. Meta stability of excited carriers were observed to arise due to electron-phonon interactions.

We build the bridge between the fiber parameters and the mode-coupling crosstalk for a graded-index six-mode fiber. Simulations show that -40dB crosstalk-level can be achieved through small core size, refractive-index value and core eccentricity.
