PhCLayout

class picazzo3.phc.generic.cell.PhCLayout

Generic Photonic Crystal Layouting Cell. The Layout of the cell is made up of a map, which is a multiline string representing the unit cells on a regular rectangular lattice. The letters in the ‘map’ correspond to unit cells in the dictionary ‘cells’.

Parameters:

name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters

The unique name of the pcell

Parameters:

ports_coordinates:

list of tuple with (coordinate (in pitches), angle, waveguide_template, [name])

zero_line_y: float

line in the map which corresponds to the coordinate y=0. This can be a fractional number, and the unit is relative to pitches.y .

purpose_hfw: PatternPurpose

drawing purpose for underetching

process_hfw: ProcessLayer

process for underetching

map: str and String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters

Map of the photonic crystal. This property accepts a multi-line string. Every character in the string represents a unit cell of the photonic crystal, which can be found in the property cells

cells: dict

dictionary of Unit Cells for a Photonic Crystal. The value should be of the form {‘x’: cell1, ‘y’: cell2}. The keys of the dictionary should be characters and each character can be used to identify the unit cell in the map

pitches: Coord2 and number >= 0

X and Y pitch of the photonic crystal

view_name: String that contains only alphanumeric characters from the ASCII set or contains _$. ASCII set is extended on PY3.

The name of the view
