We directly measure optical bound states in the continuum (BICs) by embedding a
photodetector into a photonic crystal slab. The BICs observed in our experiment are the …

Second-order topological insulators (SOTIs) have recently attracted much attention due to
their capability to support lower-dimensional topological states, namely, the corner states …

Electro-optically (EO) tunable metasurfaces have received considerable attention owing to
their capability for dynamic light field control. Here, we report an EO lithium niobate …

In this paper, a hybrid photonic-plasmonic resonator is proposed. The device consists of a
partially encapsulated 1D photonic crystal waveguide and a plasmonic nanoparticle to yield …

We characterize the performance of a quantum well infrared photodetector (QWIP), which is
fabricated as a photonic crystal slab (PCS) resonator. The strongest resonance of the PCS is …

In this Letter, we demonstrate the design, fabrication, and characterization of a photonic
crystal slab quantum cascade detector (PCS-QCD). By employing a specifically designed …

In this Letter, we propose collective topological corner modes in all-dielectric photonic
crystal (PhC) supercell arrays, where each supercell is a second-order topological insulator …

The performance of quantum well infrared photodetectors (QWIP) can be significantly
enhanced combining it with a photonic crystal slab (PCS) resonator. In such a system the …

This thesis is concerned with the tuning of resonances in photonic crystal slab (PhCS)
intersubband detectors. Quantum well infrared photodetectors (QWIPs) in the mid-infrared …

Quantum cascade lasers (QCLs) and quantum cascade detectors (QCDs) have shown
remarkable progress in their performance, availability and their use in different applications …
