“…This implies that series push-pull MZMs are the optimal choice for this particular application. Fortunately, this is one of the most typical topologies found in both LiNbO3 (x-cut) and InP modulators, so off-the-shelf high-performance components are readily available [27]- [29].…”

Abstract-Instantaneous frequency measurement receivers are a well-established technology that is used for the ultrafast characterization of pulsed microwave signals over a broad bandwidth. Recently, numerous photonic approaches to instantaneous frequency measurement (IFM) have been proposed and experimentally demonstrated, with the ultimate aim of leveraging the benefits of optical technology to improve the performance of already existent electronic solutions. Despite the numerous results, not so much attention has been paid so far to understand the subtle implications that system imperfections can have on realistic photonics-based IFM receivers. Here, we focus our attention in one of the most promising among these IFM techniques, which is based in optical power monitoring of a dual-sideband suppressedcarrier modulation after a Mach-Zehnder interferometer (MZI) filter. We develop a time domain model for the rigorous analysis of all major optical and electrical effects, including amplitude imbalance and phase errors in the modulator and the MZI, as well as on-pulse RF phase/frequency modulation. Simulations are then used to illustrate the substantial effect that a non-perfectly suppressed optical carrier can have on system performance. More importantly, it is shown that in a non-ideal situation the system amplitude comparison function critically depends with input RF power, thus greatly limiting the dynamic range of the photonicsbased receiver. Some approaches to solve these issues are also discussed.

“…Single InP-based Mach-Zehnder modulators have been improved considerably in recent years [1][2][3][4][5]. As a result, qualified high performance modulator modules for data rates of 10 -40 Gb/s became already commercially available.…”

“…The fabrication of the vertically tapered waveguide core layer and the separation of highly doped modulator sections ( Fig. 2) were achieved by using so-called enhanced selective area growth (ESAG) technology [2]. Thereby electrically isolated, reversely biased pin-junctions have been integrated into each interferometer arm of the serial periodically capacitive loaded TWE modulator section (Figs.…”

“…For example, e/o bandwidths between 10 Gb/s and 100 Gb/s can be achieved only by adapting the device parameters accordingly, which in the best case requires only updates of specific dimensions on the photolithographic masks applied during fabrication. Based on the modulator design and technology described before, a large number of single high performance MZ modulators have been already demonstrated which allow for data rates up to 100 Gb/s [1][2][3][4][5]. For example, fabricated single 43 Gb/s chirp free modulators provide < 6 dB insertion losses (IL), ≥ 20 dB extinction ratios (ER), and ≤ 2.5 V driving voltages (V π ) across 40 nm wavelength C-band [2].…”

“…Most of the components such as TIA, drivers and photodiodes are now able to provide a bandwidth suitable for 100-GBd single wavelength applications [1]. Nevertheless, modulators suffer from strong frequency-dependent loss and their 3-dB bandwidth hardly reaches 60 GHz for the best of them [2], [3]. In this context, 100-GBd applications are possible, but at the cost of very strong forward error correction algorithms, which also necessitates a data rate overhead.…”

We report a continuous-time analog equalizer based on a differential cascode amplifier cell. Realized with indium phosphide double heterojunction bipolar transistors reaching a fT/fmax couple of 370/340 GHz, this circuit exhibits a maximal peaking of 10.5 dB at 85 GHz. The tunability is made thanks to a varactor, which can tune the peaking frequency from 30 to 85 GHz. This analog equalizer also provide a bandwidth of more than 110 GHz whatever the varactor settings, which makes it suitable for very high speed applications.
