WebA semiconductor optical amplifier is an optical amplifier based on a semiconductor gain medium . It is essentially like a fiber-coupled laser diode where the end mirrors have been replaced with anti-reflection coatings; a tilted waveguide can be used to further reduce the end reflectivities. WebFeb 23, 2024 · You can solve this by knowing how to convert gain to dB: Use the formula for voltage gain in dB: dB = 20log₁₀ (V₂/V₁). Insert V₁ = 12 V and dB = -10: -10 = 20log₁₀ (V₂/12 V) -0.5 = log₁₀ (V₂/12 V) Use the antilog of the base 10: 100.5 = V₂/12 V 0.3162 = V₂/12 V V₂ = 0.3162×12 V = 3.79 V.
