Abstract: We fabricated an antireflection (AR)-coating-free semiconductor optical amplifier (SOA) with an absorbing region for an optical preamplifier. In the fabricated SOA, the resonance of light ...

Abstract: This paper describes a novel DC-coupled single input preamplifier which is robust to drift noise and variation due to the circuit operation conditions. The preamplifier is intended for ...

Another week down, and, per usual, a bunch of new tech and gadgets have been announced. This past week, Bowers & Wilkins introduced its newest noise-canceling headphones, KEF got back into the ...
