Animation
As light is amplified inside the chip an electronic device called a "P-I-N" that surrounds the laser removes excess electrons from the path of the light. By removing this fog of light-absorbing electrons, the PIN device allows the laser to sustain the beam of light.

A Continuous-Wave Raman Silicon Laser
Achieving optical gain and/or lasing in silicon has been one of the
most challenging goals in silicon-based photonics because bulk
silicon is an indirect bandgap semiconductor and therefore has a
very low light emission efficiency. Recently, stimulated Raman
scattering has been used to demonstrate light amplification and
lasing in silicon.

Silicon Shines On
Researchers are getting better at making silicon do what it really does
not like to do — emit light. A silicon laser is now demonstrated that has
promising features for future practical applications.
