Abstract: A homojunction type high-speed photodiode has an active area of greater than at least 50 microns (?m) or preferably greater than 60 microns (?m) in diameter, which has an p-i-n junction epitaxial layer formed on a semiconductor substrate and includes a first ohmic contact layer, an absorption layer, a collector layer and a second ohmic contact layer. No more absorbance occurs in the collector layer of InGaAs, by means of completely absorbing the photon energy in advance by the absorption layer in which the absorption layer has powerful optical absorption constant. Not only can the prior art problems be solved, such as surface absorbance, but also improved electron transport can be achieved by using InGaAs as the constructing material, compared to other materials. The resistance capacitance (RC) for the entire structure can be significantly reduced, and the limitations to the bandwidth resulted from the carrier transport time can be improved.

Abstract: A fiber-based, magneto-optic (MO) optical modulator or switch based on Sagnac interferometry is provided. The system uses a magneto-optic Faraday rotator (MOFR) to produce optical modulation with low magnetic fields. The Sagnac geometry allows for increased modulation at lower fields than traditional MO modulators. This switch uses the MOFR to create different states of polarization in counter-propagating waves, which results in interference at the output port. A magnetic field is used to control the amount of rotation in the state of polarization (SOP), and therefore, the ON-OFF extinction ratio.

Abstract: A photonic millimeter-wave generator capable of combining wired and wireless communication facilities to further elongate the transmission distance comprises a laser generator for generating a first optical signal; an optical frequency comb generator coupled with the laser generator; and a pulse shaper coupled with the optical frequency comb generator. The optical frequency comb generator receives the first optical signal generated by the laser generator and outputs a second optical signal. The second optical signal contains multiple frequency components and is sent to the pulse shaper. The pulse shaper adjusts the amplitude and phase of the second optical signal and then outputs the signal as a third optical signal.
