Abstract
Method and apparatus for integrating a VCSEL with a SOA, comprising positioning a collimating lens adjacent to the output of the VCSEL, positioning a focusing lens adjacent to the input of the SOA, and positioning a movable lens between the collimating lens and the focusing lens, where the movable lens has a focal length significantly longer than the focal length of the focusing lens; and moving the movable lens relative to the focusing lens so as to adjust the focusing spot on the input of the SOA.
Claims19
A method for integrating a VCSEL with a SOA, comprising:
- positioning a collimating lens adjacent to the output of the VCSEL, positioning a focusing lens adjacent to the input of the SOA, and positioning a movable lens between the collimating lens and the focusing lens, where the movable lens has a focal length significantly longer than the focal length of the focusing lens;
- and
- moving the movable lens relative to the focusing lens so as to adjust the focusing spot on the input of the SOA.
Apparatus for integrating a VCSEL with a SOA, comprising:
- a collimating lens positioned adjacent to the output of the VCSEL;
- a focusing lens positioned adjacent to the input of the SOA;
- and
- a movable lens positioned between the collimating lens and the focusing lens, where the movable lens has a focal length significantly longer than the focal length of the focusing lens.
A method for integrating a VCSEL with a SOA, comprising:
- providing a VCSEL and providing a SOA;
- and
- butt-coupling the output coupler of the VCSEL to the input facet of the SOA, wherein the output facet of the SOA is angled with respect to the input facet of the SOA and the input facet of the SOA is anti-reflection coated to prevent excessive feedback to the VCSEL.
An assembly comprising:
- a VCSEL;
- a SOA;
- the output coupler of the VCSEL being butt-coupled to the input facet of the SOA, wherein the output facet of the SOA is angled with respect to the input facet of the SOA, and the input facet of the SOA is anti-reflection coated so as to prevent excessive feedback to the VCSEL.
