ABSTRACT:
In some embodiments, a dynamic optical tag communication system is provided which includes high and low index CCR, both having a modulator, such as TCFP-MQWs on a first side of the CCR configured to modulate in a first temperature range, and a modulator on a second side of the CCR to modulate in a second temperature range. In some embodiments another high index CCR having corresponding first and second temperature range modulators is provided. In some embodiments, a CCR may have three modulators, such as MQWs, one configured to modulate in a first temperature range, another to modulate in a second temperature range, and yet another to modulate in a third temperature range. In some embodiments, a dynamic optical tag communication system has CCRs which include a high index CCR having a DDG modulator and a low index CCR having a DDG modulator.
