  Q factor and Finesse

  Two ring resonators have several spectral characteristics. Two such essential characteristics are inclusive of finesse and a Q factor. Q factor depicts the damping oscillations strength in relation to indicating a measure or the line widths relatively. There are 2 distinct definitions of resonator’s Q factor. Through storage of energy, the definition is that this factor is a stored energy ratios which is 2 pie times the dissipation per cycle of oscillation. It is equivalently known as the ratio for energy dissipation with stored energy per oscillation radian.

  On the other hand, Q factor can be defined through bandwidth of resonance. The Q factor, from this perspective, is the frequency in the resonator and the complete half width maximum resonance bandwidth. Any resonator’s Q factor is dependent upon frequencies of optical nature with power loss fractions on each trip and the time for the trip. When a resonator is such that it consists of 2 mirrors with vacuum or air between them, then the Q factor increases as the length of the resonator is enhanced (Matere et al., 2016). This is because this results in decrease in the loss of energy per the cycle of optical nature. Extremely higher values of Q, however, are achieved not through use of longer in length resonators but through reducing strongly the losses on every trip per round. An example can be quoted here that higher values of Q are gained with tiny transparent spheres whispering gallery modes.

  There are several other quantities which can be depicted in relation to the Resonator Q factor. First of all, the Q factor is equivalent to 2 pie times the exponential stored energy decay time versus the frequencies (Feng et al., 2014). Secondly, the Q factor is equivalent to 2 pie times the oscillation period number for the initial value decay of the stored energy system. The optical resonator Q factor is equivalent to the optical frequency finesse divided by the range of free spectral.
