Dielectric high-contrast sub-wavelength grating (SWG) structures have received much attention in recent years, offering a new paradigm for the integration of optical systems. Their nanoscale resonant properties can result in a complex and unintuitive

Hybrid silicon laser is a promising solution to enable high-performance light source on large-scale, silicon-based photonic integrated circuits (PICs). As a compact laser cavity design, hybrid microring lasers are attractive for their intrinsic advan

We demonstrate, for the first time, post-growth wavelength setting of electrically-injected vertical-cavity surface-emitting lasers (VCSELs) by using high-contrast gratings (HCGs) with different grating parameters. By fabricating HCGs with different

We fabricated and measured the far-field optical properties of a sub-wavelength Si3N4 (silicon nitride) two dimensional grating. Frequency-dependent transmission measurements from a white-light source revealed that both transverse magnetic (TM) and t

Sub-wavelength dielectric gratings have emerged recently as a promising alternative to distributed Bragg reflection dielectric stacks for broadband, high-reflectivity filtering applications. Such a grating structure composed of a single dielectric la

Holographic displays have long inspired science fiction writers and movie makers as the communication platform of the future. Why should we restrict ourselves to a two-dimensional screen if we can transmit our virtual selves in 3D? Despite striking a

Here we describe a diffractive backlight for a multi-view 3D display technology ideally suited for mobile applications. The backlight supports full-motion parallax in a wide view zone, and can be fabricated at low cost.

Multiview three-dimensional (3D) displays can project the correct perspectives of a 3D image in many spatial directions simultaneously. They provide a 3D stereoscopic experience to many viewers at the same time with full motion parallax and do not re

We study directional bistability in hybrid silicon microring lasers and demonstrate an unidirectional laser. Unidirectional emission is achieved by integrating a passive reflector that feeds laser emission back into laser cavity to introduce extra un

We present the design of a dielectric lens that is capable of deep-subwavelength focusing. The lens is composed of dielectric rings of complete planar geometry, thus can be easily fabricated using conventional micro-fabrication process.
