Abstract
A photonic device suitable for being optically coupled to at least one optical fiber having a first spot-size, the device including: at least one photonic component; and, a graded index lens optically coupled between the at least one photonic component and the at least one optical fiber; wherein, the graded index lens is adapted to convert optical transmissions from the at least one photonic component to the first spot size.
Claims25
A photonic device suitable for being optically coupled to at least one optical fiber having a first spot-size, said device comprising:
- at least one photonic component;
- and,
- a graded index lens optically coupled between said at least one photonic component and said at least one optical fiber;
- wherein, said graded index lens comprises at least one amorphous silicon based material having a varying index of refraction between about 2.4 and about 3.7, and is adapted to convert optical transmission from said at least one photonic component to said first spot size.
A method for optically coupling at least one photonic device having a first spot-size to at least one optical fiber having a second spot-size, said method comprising forming a graded index lens including at least one amorphous silicon based material having a varying index of refraction between about 2.4 and about 3.7, and being adapted to convert optical transmissions from said first-spot size to said second spot-size so as to be integrated with said at least one photonic device;
- wherein;
- said graded index lens is adapted to be optically coupled between said at least one photonic device and optical fiber.
