Detailed Description

Passive part of an optical hybrid.

Simple 2x4 MMI model.

Example

hybrid = OpticalHybrid_v1(struct('phase_angle', pi/2));

Signal inputs: 2 -For conventional I-Q definitions, signal goes to input 1, LO to input 2

Signal outputs: 4 -Outputs 1 and 2 are in-phase (I+ and I-, respectively) -Outputs 3 and 4 are quadrature (Q+ and Q-, respectively)

Constructor & Destructor Documentation

function OpticalHybrid_v1::OpticalHybrid_v1 ( in params )

Class constructor.

Class constructor

Parameters

param.phase_angle Hybrid phase angle [rad] [Default: pi/2]

function OpticalHybrid_v1::traverse	(	in	obj,
		in	sig,
		in	lo
	)

Traverse function.

Applies frequency shift to LO, then mixes LO with signal coherently

Parameters

sig	Input signal
lo	Input local oscillator (swapping LO and signal swaps I and Q)
