Q factor

    • dhiraj_177

      dear Sir/madam,

      I have designed a ring resonator using photonic crystal. In one design one ring is pesent & in second design two ring is present. output of first ring becomes source for second ring. Now when i calculate Q factor in single ring it is 882 but in double ring it comes 175 means it is reduced but theoretically it should be increased which is verified by transmission curve also.

      So my question is how software is calculated Q factor in case of double ring.
