By locking to the unique capacitance associated with the molecular orientation, any polarization rotation can be achieved with improved accuracy over a wide temperature range. A modified relaxation oscillator circuit that can simultaneously determine the capacitance and drive the rotator is presented.engrestrictedAccessarticle2517203632036800040933800006610.1364/OE.25.0203632-s2.0-85051456342
