Abstract:
The current–voltage characteristics and photocurrent of “monolithic” diode optical pairs optically coupled by a substrate made of InAs common for them are considered, and the possibility of using the values of the photocurrent for measuring the attenuation of the “evanescent wave” in the case of total internal reflectance in the waveguide (a substrate made of InAs)/absorbing substance under analysis interphase boundary is evaluated.
Keywords:
optical sensors, sensors for the chemical composition of matter, diode optical pairs, ATR analyzers, evanescent wave analyzers, mid-IR photodiodes, mid-IR light emitting diodes.
