An uncooled poly SiGe microbolometer for infrared detection has been fabricated and characterized. The poly SiGe thin film is deposited by ultrahigh vacuum chem
Based on the band anticrossing model, the effects of the strain-compensated layer and the strain-mediated layer on the band structure, gain and differential gai
According to electrodynamic equations in curved spacetime we consider the coupling of a linearized weak gravitational wave(GW)to a Gaussian beam passing through
Modulation instability (MI) in microstructured photonic crystal fibres is studied by using an extended nonlinear Schr6dinger equation. The roles of arbitrary hi
