Knowledge Base

This function is similar to bestoverlap but it uses expand2 to get the necessary parameters, which can be useful when an evanescent mode is involved.

 

Supported Product: MODE

 

Syntax

Description

out = bestoverlap2("test_mode");

Calculates the best overlap.

out: a string containing the name of the mode with the best overlap

test_mode: a string containing the name of a D-CARD mode

out = bestoverlap2("test_mode", x,y,z);

Calculates the best overlap.

out: a string containing the name of the mode with the best overlap

test_mode: a string containing the name of a D-CARD mode

Mode alignment can be adjusted before best overlap is calculated.

x offset

y offset

z offset

The offset is applied to the test_mode.

 

Examples

This example will calculate which of the current modes have the best overlap with the D-CARD named "test_mode". The effective index of the best mode is then returned.

 

mode_name = bestoverlap2("test_mode");

neff = getdata(mode_name,"neff");
