High-absorbance resonant-cavity-enhanced free-standing Ge photodetector for infrared detection at 1550 nm wavelength
A novel free-standing resonant-cavity-enhanced (RCE) Ge thin-film absorber is designed with a bottom distributed Bragg reflector (DBR) for infrared photodetection at 1550 nm wavelength based on a Si substrate. The free-standing structure offers a high degree of freedom in optimizing the number of pe...
