Polymer modulators in silicon photonics: review and projections.

Area of Science:

• Photonics and Materials Science
• Integrated Optics
• Semiconductor Devices

Background:

• Optical modulators are crucial components in telecommunications, data centers, and optical computing.
• Existing silicon (Si) modulators face trade-offs in power, speed, drive voltage, and footprint.
• There is a need for compact, low-voltage, high-speed modulators compatible with CMOS processes.

Purpose of the Study:

• To review Si-organic-hybrid (SOH) modulators and their integration pathways.
• To highlight the advantages of SOH devices over traditional silicon modulators.
• To discuss challenges and alternative high-performance modulator technologies.

Main Methods:

• Review of existing literature on Si-organic-hybrid (SOH) modulators.
• Analysis of material integration strategies for SOH devices.
• Comparative discussion of SOH with other advanced modulator types.

Main Results:

• SOH devices exhibit large modulation bandwidths due to strong electro-optic (EO) effects.
• SOH modulators can achieve smaller drive voltages and footprints compared to silicon.
• Challenges in SOH integration include aging and temperature stability.

Conclusions:

• Si-organic-hybrid (SOH) technology presents a viable path for next-generation optical modulators.
• Further research is needed to address integration challenges for widespread adoption.
• Alternative approaches like plasmonic-organic-hybrid (POH) and LiNbO3 modulators also offer high performance.
