锁频控制器

锁频控制器（LLP-100）是专门设计用来提升Santec外腔式可调激光器的频率功能的设备，作为伺服控制器来稳定激光器的振荡频率。LLP-100接收外部信号，并将激光波长锁定到外部参考值。LLP-100可以通过软件调节并将频率锁到理想的参考值，比如气体吸收腔、法珀腔或其他频率的参考值。频率锁定支持PDH方法和侧边锁定法（side-fringe锁频方法）。LLP-100搭配TSL-570是一套理想的系统，适用于既要求波长可调又要求频率稳定的应用场景。例如：基于硅光子微腔结构的连续光频梳发生器的应用，或者任意波长都可锁定的光量子应用。

Co-packaged optics (CPO) is revolutionizing data center and high-performance computing interconnects by integrating optical engines directly with switching ASICs. This whitepaper offers a detailed, engineer-level exploration of CPO, covering both the technological benefits and the rigorous testing requirements needed to ensure performance and reliability.

In this whitepaper, you will discover:

1. The key drivers for CPO adoption — power efficiency, bandwidth scaling, signal integrity, and form-factor optimization

2. How photonic integrated circuits (PICs) enable compact, high-density optical I/O in CPO architectures

3. Thermal challenges in co-packaged designs and best practices for thermal management during testing

4. Testing strategies for CPO modules: measuring insertion loss, return loss, polarization effects, crosstalk, and more

5. Advanced measurement solutions: how Santec’s tunable lasers, polarization synthesizers, power meters, and swept analyzers (e.g., STS system, SPA-110) can be integrated into high-precision CPO validation setups

6. Practical tips for building an automated, repeatable test flow that addresses the unique trade-offs of co-packaged optics

Whether you're developing PICs for production, characterizing module-level performance, or optimizing test processes for yield and scale, this guide shows how Santec’s measurement instruments support every aspect of CPO development.
