Fundamentals of Microwave Photonics

An Optical Technique for Radio Frequency Interference Mitigation

“…Nonetheless, this consequence could be acceptable in some systems where the alternative option is to "go blind." Numerous linearization techniques have been demonstrated for analog photonic links [8], many of which could be applied to these issues. Furthermore, while a quadrature-biased MZM ideally introduces no even order distortions, the large signal drive in the null condition may accentuate non-idealities of an MZM in the form of even-order distortion.…”

“…Assuming that the photodiode is linear, the photocurrent can be written as [8] where I dc is the average photocurrent and J is a Bessel function of the first kind having arguments φ = π V/V π with V π being the voltage required to switch the MZM from peak to null transmission. From (1), it is straightforward to determine the average output power for the SOI and INT as…”

“…Optical signal processing presents numerous advantages over traditional electronic approaches including increased bandwidth, compatibility with long-haul fiber-optic remoting and reduced size, weight and power [8]. There have been numerous demonstrations of photonic techniques for interference suppression for the applications noted above [9].…”

Resonant optical receiver design by series inductive peaking for sub-6 GHz RoF

“…1) consists of two parts. The PD itself can be modeled [2] with a current source (IPD), a junction capacitance (Cj), a shunt resistance (Rsh, which is typically negligible), and a series resistance. Secondly, the interconnect parasitics connecting the PD to the TIA are modeled as a series resistor-inductor element.…”

Акустические Колебания В Интегральных Электрооптических Модуляторах На Основе Ниобата Лития

“…В последнее время значительно возрос интерес к волоконно-оптическим системам с аналоговыми оптическими сигналами и аналоговой модуляцией. Это системы опроса и предварительной обработки сигналов волоконно-оптических датчиков [2] и радиофотонные системы генерации, пе-редачи и обработки аналоговых СВЧ-сигналов [3,4]. Здесь возбуж-даемые электрическими управляющими сигналами поверхностные и объемные акустические колебания модулятора даже на относительно Рис.…”
