Patent ID: 11868025
Assignee: LAWRENCE LIVERMORE NATIONAL SECURITY, LLC
Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 2:
3. An apparatus, comprising: a first stage including:
a first laser light source for providing first laser light;
a first Mach-Zehnder modulator (MZM) comprising a first optical arm and a second optical arm, wherein said first MZM is configured to receive at least a first portion of said first laser light into said first optical arm and at least a second portion of said first laser light into said second optical arm;
a waveform source for applying an input voltage waveform to one of said first optical arm or said second optical arm, wherein said first portion of said first laser light and said second portion of said first laser light propagate through said first MZM and interfere one with the other to produce a first output optical signal; and
a first amplified detector configured to detect said first output optical signal and produce a first output voltage waveform; and
a second stage comprising:
a second laser light source for providing second laser light;
a second MZM comprising a third optical arm and a fourth optical arm, wherein said second MZM is configured to receive at least a first portion of said second laser light into said third optical arm and at least a second portion of said second laser light into said fourth optical arm;
said first amplified detector being configured for applying said first output voltage waveform to one of said third optical arm or said fourth optical arm, wherein said first portion of said second laser light and said second portion of said second laser light propagate through said second MZM and interfere one with the other to produce a second output optical signal; and
a second amplified detector configured to detect said second output optical signal and produce a second output voltage waveform.
