Photodiodes for Detecting the Emission of Quantum-Sized Disc Lasers Operating in the Whispering Gallery Modes (2.2–2.3 μm)

Photodiodes based on solid solutions in the GaSb–InAs system are for the first time applied to study the spectral characteristics of single and coupled whispering-gallery-mode (WGM) lasers emitting in a range of 2.2–2.3 μm. The capacity of photodiodes with a photosensitive area 2.0 mm in diameter is...

Zusammenfassung:Photodiodes based on solid solutions in the GaSb–InAs system are for the first time applied to study the spectral characteristics of single and coupled whispering-gallery-mode (WGM) lasers emitting in a range of 2.2–2.3 μm. The capacity of photodiodes with a photosensitive area 2.0 mm in diameter is C = 520 pF at U = –2 V, which corresponds to a time constant of τ = 53 ns. It is shown that the parameters of the fabricated photodiodes make it possible to detect the emission of quantum-sized disc lasers at room temperature not using cryogenic cooling.
