<p>An AR coated quantum dot resonator (10) implementing a wavelength independent light source to resolve a drawback of degradation in the property of a high temperature optical output due to AR coating of LED or wavelength locked light source, which is filtered to a narrow line width, is disclosed. In one embodiment, a gain medium (13) includes at least one quantum dot and an anti-reflection (AR) coated reflection plane (12,15) at one of front (15) and rear planes (12) of the gain medium (13). The gain medium (13) has a wide line width due to different sizes and distribution of a plurality of quantum dots. The line width includes entire wavelength channels of a WDM or WDM-PON. Also, the AR coated reflection plane is a front reflection plane having a lower reflectivity (e.g., 0.001 % to 1 %.) than that of a rear reflection plane.</p> |
