Abstract
Aspects of the subject disclosure may include, a generator that facilitates generation of an electromagnetic wave, a core, and a waveguide that facilitates guiding the electromagnetic wave towards the core to induce a second electromagnetic wave that propagates along the core. The core and/or the waveguide can be configured to reduce radiation loss of the second electromagnetic wave, propagation loss of the second electromagnetic wave, or a combination thereof. Other embodiments are disclosed.
Claims23
A device, comprising:
- a generator that facilitates generation of a first electromagnetic wave;
- a core;
- and
- a waveguide that facilitates guiding the first electromagnetic wave towards the core,
- wherein the core comprises a first region, a second region, and a third region,
- wherein the core comprises an interface in the first region,
- wherein the first electromagnetic wave induces at the interface a second electromagnetic wave,
- wherein the waveguide is configured to confine the second electromagnetic wave at least in part within the core in the first region,
- wherein the second region of the core is configured to reduce a radiation loss of the second electromagnetic wave as the second electromagnetic wave propagates into the second region, and
- wherein the third region of the core is configured to reduce a propagation loss of the second electromagnetic wave as the second electromagnetic wave propagates into the third region.
A device, comprising:
- a generator that facilitates generation of a first electromagnetic wave;
- a core;
- and
- a waveguide that facilitates guiding the first electromagnetic wave towards the core,
- wherein the core comprises a first region, a second region, and a third region,
- wherein the core comprises an interface in the first region,
- wherein the interface comprises a tapered structure,
- wherein the first electromagnetic wave induces at the interface a second electromagnetic wave,
- wherein the waveguide is configured to confine the second electromagnetic wave at least in part within the core in the first region,
- wherein the second region of the core has a tapered structure and is configured to reduce a radiation loss of the second electromagnetic wave as the second electromagnetic wave propagates into the second region, and
- wherein the third region of the core is configured to reduce a propagation loss of the second electromagnetic wave as the second electromagnetic wave propagates into the third region.
A device, comprising:
- means for generating a first electromagnetic wave;
- and
- means for guiding the first electromagnetic wave towards a core,
- wherein the core comprises an interface in a first region of the core,
- wherein the first electromagnetic wave induces at the interface a second electromagnetic wave,
- wherein the interface is configured to reduce a reflection by the first electromagnetic wave at a surface of the interface,
- wherein the means for guiding confines the second electromagnetic at least in part within the core in the first region, and
- wherein the means for guiding or a second region of the core is configured to reduce a radiation loss of the second electromagnetic wave as the second electromagnetic wave propagates into the second region.
