Abstract
Forming an optical device includes growing an electro-absorption medium in a variety of different regions on a base of a device precursor. The regions include a component region and the regions are selected so as to achieve a particular chemical composition for the electro-absorption medium included in the component region. An optical component is formed on the device precursor such that the optical component includes at least a portion of the electro-absorption medium from the component region. Light signals are guided through the electro-absorption medium from the component region during operation of the component.
Claims20
An optical device, comprising:
- optical component on a base, the optical component including an electro-absorption medium through which light signals are guided during operation of the component;
- and
- dummy regions on the base, the dummy regions including the electro-absorption medium but without the electro-absorption medium that is included in the dummy regions being included in the component or in any other optical component on the base.
A method of forming an optical device, comprising:
- growing an electro-absorption medium in a variety of different regions on a base of a device precursor, the regions including a component region and being selected so as to achieve a particular chemical composition for the electro-absorption medium included in the component region;
- forming an optical component on the device precursor such that the optical component includes at least a portion of the electro-absorption medium from the component region, the component being formed such that during operation of the optical component light signals are guided through the electro-absorption medium from the component region;
- and
- completing formation of the device such that in the completed device a portion of the regions still include the electro-absorption medium and are dummy regions, where the electro-absorption medium included in dummy regions is not included in the optical component or in any other optical component on the device.
A method of forming an optical device, comprising:
- forming an electro-absorption medium in a variety of different regions on a base of a device precursor;
- and
- completing formation of the device such that the electroabsorption medium included in a portion of the regions is included in an optical component and another portion of the regions are dummy regions in that the electroabsorption medium included in the dummy regions is not included in the optical component or in any other optical component on the device,
- the optical component including the electro-absorption medium arranged such that during operation of the component light signals are guided through the electro-absorption medium included in the optical component.
