Need design a balanced photodiode detector based on an EO switch driven by an RF signal

Description

Question:

Design a balanced photodiode detector based on an EO switch driven by an RF signal, for example, to detect interstellar RF radiation and noise fluctuations with very precision.

• Include a descriptive diagram
• Define the following:

> The optical source

> The EO switch material & dimensions, and driving (Voltage) conditions

> The balanced photodiode: types & response

> Any additional necessary optics

Requirement:

Need to show the complete calculations and provide proof of the process. Diagram should draw by hand.
