Abstract
One or more single mode waveguide devices are fiber coupled such that signals to an optical element affect the coupling of the waveguide device to one or more on chip modulators and to an optical fiber. The optical element or additional optical elements are controlled to adjust the coupling of the waveguide device to an on chip modulator and to an optical fiber.
Claims44
An optical transmission apparatus comprising:
- at least one laser provided on a chip;
- at least one optical element;
- and
- at least one modulator provided on the chip, such that light from the at least one laser is directed into the at least one modulator by the at least one optical element.
1 more element
An optical transmission control apparatus comprising:
- emitting means for emitting light;
- modulation means coupled to the emitting means;
- and
- optical means for directing light having a particular wavelength from the emitting means into the modulation means.
1 more element
An optical transmission method comprising:
- selecting at least one laser on a chip, the at least one laser emitting light;
- establishing an optical path from the selected laser to at least one modulator on the chip;
- and
- adjusting the optical path to adjust output power from the at least one laser to the at least one modulator.
