“…As we seek to utilize an ever-increasing portion of the electromagnetic spectrum for next generation communications and radar systems, microwave-photonic signal processing platforms show great promise for their ability to manipulate signals at high frequencies and over extremely wide bandwidths [1][2][3]. Rapid progress in the field of silicon photonics has also enabled the integration of high-speed modulators [4,5], amplifiers [6][7][8] and detectors [9] with electronic and photonic circuitry [10][11][12][13], opening the door to miniaturization of radio-frequency (RF) photonic circuits having signal processing performance that is competitive with established microwave technologies [14,15]. However, it remains challenging to implement narrow-band filtering using all-optical techniques, as ultra-low loss waveguides are needed to store signals for long periods of time [16][17][18].…”

Microwave photonic systems are compelling for their ability to process signals at high frequencies and over extremely wide bandwidths as a basis for next generation communication and radar technologies. However, many applications also require narrow-band (∼ MHz) filtering operations that are challenging to implement using optical filtering techniques, as this requires reliable integration of ultra-high quality factor (∼ 10 8 ) optical resonators. One way to address this challenge is to utilize long-lived acoustic resonances, taking advantage of their narrow-band frequency response to filter microwave signals. In this paper, we examine new strategies to harness a narrow-band acoustic response within a microwave-photonic signal processing platform through use of light-sound coupling. Our signal processing scheme is based on a recently demonstrated photon-phonon emitter-receiver device, which transfers information between the optical and acoustic domains using Brillouin interactions, and produces narrow-band filtering of a microwave signal. To understand the best way to use this device technology, we study the properties of a microwave-photonic link using this filtering scheme. We theoretically analyze the noise characteristics of this microwave-photonic link, and explore the parameter space for the design and optimization of such systems. *

We formulate and experimentally validate an equivalent-circuit model based on distributed elements to describe the electric and electro-optic (EO) properties of travellingwave silicon-organic hybrid (SOH) slot-waveguide modulators. The model allows to reliably predict the small-signal EO frequency response of the modulators exploiting purely electrical measurements of the frequency-dependent RF transmission characteristics. We experimentally verify the validity of our model, and we formulate design guidelines for an optimum trade-off between optical loss due to free-carrier absorption (FCA), electro-optic bandwidth, and π-voltage of SOH slot-waveguide modulators.

“…The public and private investment in R&D has led to a rapid development of silicon photonics technologies in the last two decades. CMOS pilot lines and advanced research institutes [10]- [17] have played a pivotal role by: (a) continuously evolving and maturing the technology platforms to reach a high Technology Readiness Level (TRL) 1 ; and (b) making these platforms accessible with minimal restriction and at lowcost to third parties for validating their design innovations. This open-access model enables an economically viable and low-barrier access to fabless companies where such companies bank on the off-the-shelf Intellectual Property (IP) and technology processes of pure-play foundries for PIC prototyping and manufacturing.…”
