Frequency response and bandwidth enhancement in Ge/Si avalanche photodiodes with over 840 GHz gain-bandwidth-product.
In this work we report a separate-absorption-charge-multiplication Ge/Si avalanche photodiode with an enhanced gain-bandwidth-product of 845 GHz at a wavelength of 1310 nm. The corresponding gain value is 65 and the electrical bandwidth is 13 GHz at an optical input power of -30 dBm. The unconventional high gain-bandwidth-product is investigated using device physical simulation and optical puls...
متن کاملGain-Bandwidth Characteristics of Thin Avalanche Photodiodes
The frequency-response characteristics of avalanche photodiodes (APDs) with thin multiplication layers are investigated by means of a recurrence technique that incorporates the history dependence of ionization coefficients. In addition, to characterize the autocorrelation function of the impulse response, new recurrence equations are derived and solved using a parallel computer. The mean freque...
متن کاملMonolithic germanium/silicon avalanche photodiodes with 340 GHz gain–bandwidth product
Significant progress has been made recently in demonstrating that silicon photonics is a promising technology for low-cost optical detectors, modulators and light sources1–12. It has often been assumed, however, that their performance is inferior to InP-based devices. Although this is true in most cases, one of the exceptions is the area of avalanche photodetectors, where silicon’s material pro...
متن کاملEnhanced Gain-Bandwidth Product and Performance in Thin Heterostructure Avalanche Photodiodes
It is well known that the excess noise factor of an avalanche photodiode (APD), which is a measure of its gain fluctuation, can be reduced by decreasing the thickness of the avalanche multiplication region. This noise reduction is attributable to the increased importance of the dead-space effect in thin layers, which prevents a carrier from impact ionizing before it travels a sufficient distanc...
متن کاملHigh speed InAs electron avalanche photodiodes overcome the conventional gain-bandwidth product limit.
High bandwidth, uncooled, Indium Arsenide (InAs) electron avalanche photodiodes (e-APDs) with unique and highly desirable characteristics are reported. The e-APDs exhibit a 3dB bandwidth of 3.5 GHz which, unlike that of conventional APDs, is shown not to reduce with increasing avalanche gain. Hence these InAs e-APDs demonstrate a characteristic of theoretically ideal electron only APDs, the abs...
