A phase modulated (PM) microwave photonic link (MPL) with linearity improvement is presented. The link demodulates the PM using a phase discriminator based on a dynamically tunable, integrated, sixth-order optical lattice filter in planar lightwave circuit (PLC) technology. The linearity of the demodulation process is optimized by using electrical spectrum monitoring and a feedback algorithm to automatically...
Ultrafast optoelectronic devices are useful in prescribing fast microwave and millimeter-wave waveforms of wide bandwidth and precision. An integrated InP PIC will be illustrated to demonstrate agile arbitrary waveform synthesis at time domain.
CMOS electronic photonic integrated circuit provides an important technology for producing ultra wide band signal processors with low cost and high level of integration. Recent developments of CMOS based photonic devices have shown promising results. In this paper we will review and present the RF performances of widely tunable microwave photonic filters fabricated with production CMOS processes.
