Abstract-This study presents the recently developed monolithic photonic-integrated circuits that provide efficient amplitude modulation for wavelength division multiplexed optical channels. The circuits were designed for application as a read-out unit in a highenergy physics experiment, and are sufficiently general to be applied in various types of high-speed photonic transmitters. They were constructed using basic building blocks provided in an indium phosphide-based generic integration technology process and fabricated in a multi-project wafer run. Two variants of the circuits, utilizing modulators in Mach-Zehnder and Michelson interferometer configuration, are discussed. A modulation bandwidth of 18.6 GHz was measured and error-free transmission of a 10-Gb/s signal through 85 km of optical fiber was achieved.Index Terms-Electro-optical amplitude modulator (AM), indium phosphide (InP), generic integration technology, MachZehnder interferometer, Michelson interferometer, multi-project wafer (MPW), photonic integrated circuit, wavelength division multiplexing (WDM).

A Photonic-Integrated Transceiver for Data Readout Systems

“…The modulator has been driven in a single-ended configuration, which allows using a simpler electrical submount as well as reduces the cost and energy consumption of the driver. Previous experiments with similar modulators confirmed the possibility of transmitting 10 Gb/s signals over 50 km with a BER below 10 −10 [6], [10]. As the optical carrier CW laser light at λ = 1550 nm was used.…”

“…All of them have been used to realize the photonic transceiver. A detailed description of the properties and performance of these elements can be found in [4], [6].…”

300 GHz Optoelectronic Transmitter Combining Integrated Photonics and Electronic Multipliers for Wireless Communication

“…Evolving from colliding pulse ML, multiple colliding pulse ML features and multiple SAs concatenated with gain sections, for repetition rates multiplication >2 as has been extensively investigated [20,21]. Recently, a new class of on-chip broadband reflector based on the multimode interference (MMI) principle has been proposed [22] and demonstrated its wide applicability [23,24]. Such multimode interference reflectors (MIRs) are simple to create in lithography with greater fabrication tolerance to replace DBRs and cleaved facets.…”

InP photonic circuits using generic integration [Invited]

“…Recently the concept has been implemented to create the integrated, facet-free Michelson interferometer shown in Fig. 9 [32]. These have also been implemented in on-chip interferometers and precision cavities for mode-locked lasers [16] and provide the precision required for a new generation of precision-controlled coupled-cavity lasers [33].…”
