Portland, Ore. – Cornell University says it has fabricated the components necessary for silicon optical computers that use light instead of electrons. “Photonic microchips are now a reality,” said ...

Tufts University engineers have invented a chip-sized, high-speed modulator that operates at terahertz (THz) frequencies and at room temperature at low voltages without consuming DC power. The ...

Just as light have different polarization when propagating in free space, there are similar properties in integrated optical waveguides, we call it ‘TE’ polarization and ‘TM’ polarization. The ...
