The application fields of infrared photodetectors are quite extensive. Compared with
traditional infrared photodetection materials such as IV and III–V semiconductors, newly …

In this letter we present a quantum well infrared photodetector (QWIP), which is fabricated as
a photonic crystal slab (PCS). With the PCS it is possible to enhance the absorption …

Photonic crystal nanobeam cavities are valued for their small mode volume, CMOS
compatibility, and high coupling efficiency-crucial features for various low-power photonic …

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 …

We report the development of a front-side contact design for thermophotovoltaics that utilizes
metallic photonic crystals (PhCs). While this front-side grid replacement covers more surface …

In this work we study the effect of thin-film deposition on the quality factor (Q) of silicon
nanobeam cavities. We observe an average increase in the Q of 38±31% in one sample and …

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 …

Quantum dots are excellent sources of on-demand single photons and can function as
stable quantum memories. Additionally, advanced fabrication techniques of III-V materials …

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 …
