| An self-oscillating parametric optical transducer based on a quantum double-barrier heterostructure is proposed, the basic element of which is a tunnel-resonant diode, and it acts as a primary optical transducer and as an selfoscillating, which greatly simplifies the design of the optical transducer. Based on the consideration of physical processes in the tunnel-resonant diode, a mathematical model of the optical transducer was developed, on the basis of which the parametric dependence of the conversion and sensitivity functions was obtained. It is shown that the main contribution to the change of transformation functions and sensitivity is introduced by a change in optical power. This causes a change in the negative differential resistance of the oscillating system of the self-oscillating of the transducer, which, in turn, changes the output frequency of the device. At the same time, the internal capacitance and inductance also depend on the action of the optical power, but these changes do not affect the output frequency, since the external capacitance and inductance are four orders of magnitude greater than the internal capacitance and inductance of the tunnel-resonant diode. The sensitivity of the optical transducer varies from 15.27 kHz/μW/cm2 to 16.37 kHz/μW/cm2 in the measuring power range from 0 to 100 μW/cm2. |
