Modulation on Silicon for Datacom: Past, Present, and Future (Invited Review)

Abstract: Datacenters become an important part of technical infrastructure. The Datacom traffic grows exponentially to satisfy the demands in IT services, storage, communications, and networking to the growing number of networked devices and users. High bandwidth and energy efficient optical interconnects are critical to improve overall productivity and efficiency in data centers. Mega-data centers are expected to address the power consumption and the cost in which optical interconnects contribute quite a large part. Si… Show more

“…The development trend is towards higher integration for higher bandwidth density and lower cost per gigabit. Silicon photonics is a promising technology that has been widely used for applications in optical communication [8,9], optical switch [10,11], optical computing [12,13], light detection and ranging (LIDAR) [14,15], optical sensing [16][17][18], and so on and so forth. Due to the complementary metal-oxide-semiconductor (CMOS) compatible process and the high integration capability, silicon photonics has shown superior performance in aforementioned applications.…”

“…Although silicon MRM offers a very high extinction ratio (ER) and low device footprint, its performance is severely dependent on operating wavelength (λ) and temperature [9]- [11]. On the other hand, silicon based MZM suffers from large device footprint and significant power consumption [12]- [14]. To reduce the footprint of MZM, compact and highly efficient optical phase shifters (PS) are required.…”
