The steady increase in volume of data transfer will ultimately lead to a
need for a radically new approach to telecommunication. Incremental
approaches in electronic speeds are reaching the physical limits of what
is possible. With optical pulses of a few tens of femtoseconds (fs)
that are routinely produced, digital communication could in principle
reach a rate of tens of THz. The fundamental difficulty in exploiting
the high potential data rate of femtosecond optical pulses is that the
original signal to be transmitted is at a much slower clock rate, in the
GHz rather than THz range.
The invention pertains to the stabilization of lasers in general, and
mode-locked lasers in particular. Undesirable excursions of the cavity
mode frequency are caused when the laser cavity length is changed by
vibrations. The excursions occur on the order of tens of MHz. It is
the first purely optical auto-stabilizing system; and it is advantageous
because it eliminates the error associated with electrical and/or
mechanical stabilization. A highly stable mode frequency allows for
many new application areas to be explored.
This purely solid state system, without moving parts nor liquid dye
jets achieves a resolution of less than 1 Hz using a hybridly
mode-locked laser system. It can easily be miniaturized for different
The extremely high rate of accuracy and stability that can be achieved
in mode-locked lasers makes the vision of 10 THz bit rate communication
