Photonic technologies are a key area at Gradiant, enabling next-generation communications, quantum systems, and advanced sensing platforms. We develop integrated photonic circuits that address critical challenges such as spectral efficiency and signal integrity.
A major innovation is the design of photonic circuits for analog self-interference cancellation in STAR systems, allowing simultaneous transmission and reception on the same frequency channel and improving bandwidth utilization. We also lead the development of compact architectures for quantum sensors based on NV centers, capable of operating across a wide frequency range (from DC to tens of THz).
Our multidisciplinary approach combines expertise in photonics, quantum physics, microelectronics, and embedded software. These technologies play a crucial role in strengthening European digital sovereignty and leadership within the global photonics and quantum ecosystem.
At Gradiant, we design and develop integrated photonic circuits that enable more efficient, compact, and scalable communication systems. These platforms address challenges such as spectral efficiency, latency reduction, and signal integrity, critical factors for next-generation network deployment and quantum applications. One of our key innovations is analog self-interference cancellation in full-duplex (STAR) systems, which allows simultaneous transmission and reception on the same frequency channel, optimizing spectrum utilization. We also work... Continue reading
Photonic signal processing has become an essential alternative to traditional electronics, overcoming limitations in speed, energy efficiency, and integration capacity. At Gradiant, we explore how to harness light to perform filtering, multiplexing, and signal manipulation with far greater precision than conventional systems. These capabilities are particularly relevant in advanced telecommunications, quantum platforms, and defense systems, where reliability and bandwidth are critical. Our solutions enable low-power, high-density architectures that... Continue reading
