Want to boost your next-gen photonic applications? Imec is looking into high-performance integrated photonics electro-optic devices (HI-PED) to increase the performance of silicon photonics.
What does the future of silicon photonics look like?
On the one hand, we’re looking at more innovative materials that deliver a higher performance, especially for applications such as:
On the other hand, we want to hold on to silicon’s many advantages: affordability, scalability and integration potential.
Can we go beyond silicon photonics without losing its benefits? That’s what imec’s HI-PED program wants to achieve, by exploring new materials and integrating them into imec’s existing silicon photonics platform.
If you want to enhance the performance of an integrated photonic circuit, the modulator is a critical bottleneck. The bandwidth it needs to manipulate increasing amounts of data is fast approaching what silicon can accommodate.
The refractive index of electro-optic materials changes when a voltage is applied to them – leading to a phase shift of the signal that passes through. They show no loss, and a low voltage leads to a large phase shift. This enables the creation of extremely efficient devices that modulate at high frequencies while consuming very little power.
That makes electro-optic materials ideal for building high-performing and energy-efficient modulators. Especially if they can be integrated with silicon photonics components.
Imec is looking at two promising electro-optic materials:
Thanks to its combined expertise in material science, circuit design, and foundry technologies, imec is ideally positioned to address these challenges and enable the integration of TFLN (in the near term) and BTO (in the long term) in a silicon photonics platform.
Imec’s HI-PED research can provide a breakthrough for photonic applications that urgently need to crack current performance limitations.
