We report here broadband membrane reflectors based on Fano resonances in patterned silicon
nanomembranes. Resonance control of the reflectors was realized either by partially removing
buried oxide layer underneath the ...

Large-area (3x3 mm2) flexible photodetectors were realized, based on crystalline InP
semiconductor nanomembranes transferred to flexible polyethylene terephthalate substrates. Very
low dark current a few microamperes ...

We report here the characteristics of surface-normal optical filters based on Fano resonances on
patterned single crystalline silicon nanomembranes SiNMs , which were fabricated and transferred
onto transparent plastic ...

We propose and report an encapsulated photonic crystal concept for efficient electrical injection of
photonic crystal surface-emitting lasers. Detailed rate equation analysis reveals a significant
threshold current ...
