Abstract
A multi-frequency light source is disclosed. In one disclosed aspect, the light source may comprise a gain region defined by a first and second mirror. The gain region may have corresponding resonant modes. An external cavity defined by a third mirror and said second mirror is also provided, with the external cavity having a plurality of resonant modes. The second mirror may be terminated with a layer of high reflectivity. In a further aspect, the second mirror may be terminated with an antiphase layer.
Claims17
An equalized light source comprising:
- a gain region defined by a first and second mirror, said second mirror being formed from alternating layers of n-low and n-high materials, and said gain region having a corresponding gain response;
- an external cavity defined by a third mirror and said second mirror, said external cavity having a corresponding response shape;
- and
- wherein said second mirror is terminated with a layer of n-high material.
A light source comprising:
- a gain region defined by a first and second mirror, said gain region having a corresponding peaked gain response shape having a local maximum;
- an external cavity defined by a third mirror and said second mirror, said external cavity having a corresponding response shape defined by a passband having a local minimum interspersed between a pair of local maximums;
- and
- wherein a corresponding response of said second mirror is chosen so as to form a substantially flat output response when superimposed over said peaked gain response shape.
A light source comprising:
- a gain region defined by a first and second mirror, said gain region having a corresponding peaked gain response shape having a local maximum;
- an external cavity defined by a third mirror and said second mirror, said external cavity having a corresponding response shape defined by a passband having a local minimum interspersed between a pair of local maximums;
- and
- wherein a corresponding response of said second mirror is chosen so as to be substantially complimentary in shape when compared to said peaked gain response.
