Lithium tantalate (LTOI) high speed electro-optic modulator
Lithium tantalate (LTOI) high speed?electro-optic modulator
Global data traffic continues to grow, driven by the widespread adoption of new technologies such as 5G and artificial intelligence (AI), which poses significant challenges for transceivers at all levels of optical networks. Specifically, the next generation electro-optic modulator technology requires a significant increase in data transfer rates to 200 Gbps in a single channel while reducing energy consumption and costs. In the past few years, silicon photonics technology has been widely used in the optical transceiver market, mainly due to the fact that silicon photonics can be mass-produced using the mature CMOS process.
However, SOI electro-optic modulators that rely on carrier dispersion face great challenges in bandwidth, power consumption, free carrier absorption and modulation nonlinearity. Other technology routes in the industry include InP, thin film lithium niobate LNOI, electro-optical polymers, and other multi-platform heterogeneous integration solutions. LNOI is considered to be the solution that can achieve the best performance in ultra-high speed and low power modulation, however, it currently has some challenges in terms of mass production process and cost.
Recently, the team launched a thin film lithium tantalate (LTOI) integrated photonic platform with excellent photoelectric properties and large-scale manufacturing, which is expected to match or even exceed the performance of lithium niobate and silicon optical platforms in many applications. However, until now, the core device of?optical communication, the ultra-high speed electro-optic modulator, has not been verified in LTOI...
