Abstract In 1987, Yablonovitch and John proposed an artificial dielectric structure known as
Photonic crystals (PhCs) consisting of periodic and random variation of the refractive index …

The arrival of the big data era has driven the rapid development of high-speed optical
signaling and processing, ranging from long-haul optical communication links to short-reach …

A low operating energy is needed for nanocavity lasers designed for on-chip photonic
network applications. On-chip nanocavity lasers must be driven by current because they act …

We demonstrate a continuous wave (CW) sub-wavelength metallic-cavity semiconductor
laser with electrical injection at room temperature (RT). Our metal-cavity laser with a cavity …

We describe the growth of InP layer using an ultrathin III-V active layer that is directly bonded
to SiO_2/Si substrate to fabricate a buried heterostructure (BH) laser. Using a 250-nm-thick …

Recently a novel photonic integration technology, based on a thin InP-based membrane, is
emerging. This technology offers monolithic integration of active and passive functions in a …

We review recent developments in directly modulated lasers (DMLs) with low operating
energy for datacom and computercom applications. Key issues are their operating energy …

The power consumption of a conventional photoreceiver is dominated by that of the electric
amplifier connected to the photodetector (PD). An ultralow-capacitance PD can overcome …

In many application scenarios, silicon (Si) photonics favors the integration of III-V gain
material onto Si substrate to realize the on-chip light source. In addition to the current …

We present a new fab-in-the-loop reinforcement learning algorithm for the design of nano-
photonic components that accounts for the imperfections present in nanofabrication …
