Metal contacts on semiconductors devices are normally defined by lift-off process, because no well-defined etch processes exist for some rare metals. In this work, an RIE process for gold contacts is introduced which requires a high-density plasma, g

A novel long-wavelength vertical-cavity surface-emitting laser (VCSEL) structure based on a subwavelength high-contrast grating (HCG) as the output mirror has been realized. By design, these devices are highly polarization stable, are single mode at

The availability of silicon photonic integrated circuits (ICs) in the 2–4 μm wavelength range enables miniature optical sensors for trace gas and bio-molecule detection. In this paper, we review our recent work on III–V-on-silicon waveguide circ

We experimentally demonstrate the generation of 107-Gbit/s net-rate optical discrete multitone signal using a 1.5- μ m single-mode vertical cavity surface emitting laser (VCSEL) with modulation bandwidth of 22 GHz. Utilizing a nonlinearity-tolerant

Nonlinear metasurfaces are advancing into a new paradigm of "flat nonlinear optics" owing to the ability to engineer local nonlinear responses in subwavelength-thin films. Recently, attempts have been made to expand the design space of nonlinear meta

Optically-thin nonlinear polaritonic metasurfaces created by coupling of intersubband nonlinearities in semiconductor heterostructures with optical modes in nanoresonators have recently demonstrated efficient three-wave-mixing at very low pumping int

We report giant nonlinear circular dichroism for second- and third-harmonic generation from nonlinear chiral polaritonic metasurfaces. Experimentally, over 86% of circular dichroisms for the two harmonic generations on one-chip system around 10 pm we

We report broadband second-harmonic generation based on Stark-tunable intersubband nonlinearities in multiple-quantum-well structures combined with plasmonic nanoresonators. Experimentally, 0.75 pm of the second-harmonic generation spectral peak tuni

The efficiency limiting mechanisms in type-I GaInAsSb-based quantum well (QW) lasers, emitting at 2.3 μm, 2.6 μm and 2.9 μm, are investigated. Temperature characterization techniques and measurements under hydrostatic pressure identify an Auger pr
