We demonstrated the distributed optoelectronic properties enabled by graphene Bragg gratings (GBGs) to realize a hybrid single mode laser on silicon. A remarkable side-mode suppression ratio (SMSR) of 48 dB is achieved, benefitting from the complex coupling of the GBGs.

A current injection efficiency model is developed to identify and understand the limiting factors of the internal quantum efficiency in the GaN:Eu based red LEDs. Through this model the design and fabrication of high efficiency GaN:Eu devices in the red spectra regime is feasible.

In the context of non-Hermitian photonics, we present recent results of wave control in disordered media. We show how engineering the imaginary part of the refractive index can lead to complete wave control inside a disordered scattering system. Perfect transmission and focusing can be achieved.

Cycling excitation process (CEP) is a signal amplification mechanism showing high gain, low noise at low operation bias1,2. Depending on Auger excitation that involves localized states, CEP effect may be prominent in amorphous silicon, which has abundant localized states as a disordered material. Here we present a carbon-doped amorphous Si photodiode with ultra-high gain-bandwidth product with exceedingly low excess noise factor.

Spontaneous chiral symmetry breaking is a ubiquitous property in nature and diverse fields of modern physics. However, such symmetry breaking has been elusive experimentally in the optical systems, which usually demands multiple identical subsystems [1]. As a prominent photonic device, the ultrahigh-Q whispering-gallery mode (WGM) microresonator supports clockwise (CW) and counterclockwise (CCW) propagating waves coupled to each other, leading to symmetric and antisymmetric standing-wave modes with equal CW and CCW amplitudes. The demonstrations of such overall chirality have to rely on external perturbations to a resonator, either by breaking the parity or time-reversal symmetry [2,3]. The chirality with unbalanced CW and CCW components not only attracts general interest in physics, but also is of importance in novel devices [2,3]. Here, we experimentally demonstrate the spontaneous chirality in a single WGM microresonator (Fig. 1) without any explicit breaking of parity or time-reversal symmetry.

We propose a compressive approach to optical mode analysis of a light beam in an arbitrary basis from a small set of interferogram samples. This yields significant reduction in acquisition time and reconstruction complexity without modifying the native optical interferometer or introducing additional hardware components.
