MZM-P70

The MZM-P70 is a cutting-edge Packaged Mach-Zehnder Modulator engineered for ultra-fast electro-optic modulation in the C band. In addition, a 3-dB bandwidth exceeding 70 GHz, this high-performance modulator is the ideal choice for prototyping, proof-of-concept development, and real-world system evaluation.

Furthermore, if you’re working in analog or digital transmission, measurement systems, or emerging quantum technologies, the MZM-P70 delivers robust performance in a benchtop-ready form factor.

Key Features

3-dB electro-optic bandwidth >70 GHz
Lumped, low-capacitance RF design, high-speed connectors

Description

The MZM-P70 Packaged Mach-Zehnder Modulator is a high-performance electro-optic modulation solution optimized for C band operation. Designed specifically for fast prototyping, benchtop testing, and proof-of-concept development, this modulator brings the power of plasmonic technology into a user-friendly form factor.

Unlike chip-level solutions, the MZM-P70 comes as a fully packaged module with reinforced fiber interfaces and a standard 1 mm female RF connector. This design ensures simple handling, reliable connectivity, and integration into existing test equipment without the need for custom fixtures.

Its lumped, low-capacitance RF design and high-speed connectors support signal integrity across wide bandwidths while minimizing insertion losses.

Therefore, if you’re developing analog links, working on digital transmission formats like PAM-4 or PAM-8, or exploring quantum photonics, the MZM-P70 Packaged Mach-Zehnder Modulator provides the performance and flexibility needed to push your project forward.

Thanks to its high extinction ratio (>25 dB) and compact size, it delivers clean modulation and stable operation, even under demanding conditions.

Engineers and researchers working with short-reach links, lab test setups, or optical signal processing systems will benefit from the plug-and-play usability of this device.

C Band 145 GHz 4-channel Mach-Zehnder Modulator

MZ4-C145

Our 4-channel Mach-Zehnder Modulator MZ4-C145 is leveling-up your system integration by combining 4 MZM into one single chip. Specifically, aimed at high-performance systems with increasing complexity, in general this chip is the first of its kind with 800G throughput from one single die and 4 channels.

Key Features

3-dB electro-optic bandwidth >145 GHz
4 independent MZM channels
C-band operation
Lumped, low-capacitance RF design
Chip dimensions 1.5 mm x 2 mm

Description

Polariton’s plasmonic Mach-Zehnder Modulator (MZM) is designed for high-performance electro-optic applications. Overall, each modulator arm is precisely engineered to balance and suppress the signal in the opposite arm, achieving an optimized extinction ratio. Thus, making it an ideal solution for measuring instruments, radio-over-fiber (RoF) systems, high-data-rate optical transmissions, and microwave photonics (MWP) setups. Hence, the product is available in balanced and C band variants, subsequently being able to suit a wide range of integration needs.

Subsequently, the optical spectrum of the balanced Mach-Zehnder Modulator features a Gaussian profile, centered around the coupling wavelength of its grating couplers. Simultaneously enabling stable operation over a 3-dB optical bandwidth of approximately 60 nm. Following a built-in thermo-optic phase shifter is allowing users to fine-tune the operating point by shifting the entire spectrum along the y-axis.

Therefore, if you need a bare chip or a semi-packaged solution, this plasmonic MZM can be tailored to meet your performance and integration requirements. Finally, as part of Polariton’s portfolio of cutting-edge modulators and photonic integrated circuits, excelling at bandwidth, low power consumption, and seamless C-band operation for next-generation optical systems.

O/C Band 145 GHz Mach-Zehnder Modulator

MZM-C145

These modulators deliver unprecedented bandwidth making them an undisputed option to implement high-performance transceivers. Together with an optimized driver they provide substantial contribution to reduce system power dissipation and enhancing signal integrity. Its compact, efficient design enables seamless integration and scalability.

Key Features

3-dB electro-optic bandwidth >145 GHz
Lumped, low-capacitance RF design
Chip dimensions 1.5 mm x 2 mm
O/C band operation
Balanced (bMZM) or imbalanced (iMZM) geometry variants
Available as single or 4-channel device (MZ4-C145)

Description

The plasmonic Mach-Zehnder Modulator (MZM) features two carefully engineered arms that balance each other to enhance or subtract each other to achieve best extinction ratio for applications in measurement instruments, radio-over-fiber (RoF), high-data-rate optical transmission or microwave photonics setups (MWP). Polariton offers the product in balanced and imbalanced, optical O and C band variants.

The optical spectrum of the balanced MZM has a gaussian shape around the central coupling wavelength of its grating couplers. This allows operation in a 3-dB optical bandwidth of around 60 nm. To set the operating point, the balanced MZM contains thermo-optic phase-shifter, which shifts the whole spectrum in the y-axis.

The imbalanced MZM has a resonant spectrum with peaks and extinctions. This allows for a change of the operating point by tuning the wavelength of the laser source, making an additional voltage unnecessary.

Delivered as a chip or semi-packaged chip, this product can be tailored to your needs.
