Abstract
A microchip may include an optical clocking system. The optical clocking system may include a ring resonator which multiplies the frequency of light pulses from a light source for use as optical clocking signals and distribution waveguides to distribute the optical clocking signals to different regions of the microchip.
Claims23
An apparatus comprising:
- a waveguide formed into a closed loop, the loop having an optical path length operative to multiply a frequency of pulses from a light source,
- wherein the optical path length is A*(1−1/x), where A is an optical path length a pulse travels before the next pulse enters the closed loop and x is a multiplication factor.
An apparatus comprising:
- a waveguide formed into a closed loop, the loop having an optical path length operative to multiply a frequency of pulses from a light source,
- wherein the optical path length is A*(1+1/x), where A is an optical path length a pulse travels before the next pulse enters the closed loop and x is a multiplication factor.
A system comprising:
- a light source;
- a waveguide on a microchip, the waveguide being formed into a closed loop having an optical path length operative to multiply a frequency of pulses from the light source;
- and
- a delivery waveguide to couple light pulses from the light source into the closed loop,
- wherein the optical path length is A*(1−1/x), where A is an optical path length a pulse travels before the next pulse enters the closed loop and x is a multiplication factor.
