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 modulators and to an optical fiber. The optical element or additional optical elements are controlled to adjust the coupling of the waveguide device to a modulator and to an optical fiber.
Claims70
An optical transmission apparatus comprising:
- a laser emitting a continuous optical signal;
- a modulator;
- an adjustable element steering the optical signal to a position on the modulator;
- and
- a controller manipulating the adjustable element to maintain the optical signal to a specific position on the modulator.
2 more elements
An optical transmission method comprising:
- selecting a laser from an array of lasers, each laser emitting light at differing wavelengths;
- establishing an optical path from the laser to a modulator;
- and
- adjusting the optical path to adjust output power from the modulator.
1 more element
An optical transmission control apparatus comprising:
- at least one laser;
- at least one optical element;
- and
- at least one modulator, 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 having different wavelengths;
- modulation means;
- and
- optical means for directing light having a particular wavelength from the emitting means into the modulation means.
