Abstract
A photonics device is described. The photonics devices include at least one electrode and a waveguide. The waveguide includes electro-optic material(s), a ridge, and a slab. A first portion of the waveguide is proximate to the electrode(s), while a second portion of the waveguide includes a bend. The ridge includes a first side and a second side opposite to the first side. Portions of the slab are proximate to the first side and the second side of the ridge in the first portion of the waveguide. A portion of the slab is omitted in the second portion of the waveguide.
Claims19
A photonics device, comprising:
- at least one electrode;
- and
- a first waveguide and a second waveguide, the first waveguide including at least one electro-optic material, a ridge, and a slab, a portion of the first waveguide being proximate to the at least one electrode, the second waveguide including a bend, the ridge including a first side and a second side opposite to the first side, portions of the slab being proximate to the first side and the second side of the ridge in the portion of the first waveguide, a portion of the slab being omitted proximate to the second waveguide, the second waveguide including an other optical material, the first waveguide being optically coupled to the second waveguide such that an optical mode is transferred from the first waveguide to the second waveguide;
- wherein the slab is tapered proximate to the second waveguide to precondition the optical mode to negotiate the bend in the other optical material of the second waveguide.
A photonics device, comprising:
- a plurality of electrodes;
- and
- at least one waveguide including a first waveguide and a second waveguide the first waveguide including at least one thin film lithium-containing electro-optic material, the first waveguide including a ridge, and a slab, a portion of the first waveguide being between two electrodes of the plurality of electrodes, the second waveguide including a bend, the slab extending between the ridge and the two electrodes of the plurality of electrodes in the portion of the first waveguide, the bend having an inner region and an outer region, a portion of the slab being omitted proximate to the second waveguide, the second waveguide including an other optical material, the first waveguide being optically coupled to the second waveguide such that an optical mode is transferred from the first waveguide to the second waveguide;
- wherein the slab is tapered proximate to the second waveguide to precondition the optical mode to negotiate the bend in the other optical material of the second waveguide.
A method, comprising:
- providing at least one electrode;
- and
- providing a first waveguide and a second waveguide, the first waveguide including at least one electro-optic material, a ridge, and a slab, a portion of the first waveguide being proximate to the at least one electrode, the second waveguide including a bend, the ridge including a first side and a second side opposite to the first side, portions of the slab being proximate to the first side and the second side of the ridge in the portion of the first waveguide, a portion of the slab being omitted proximate to the second waveguide, the second waveguide including an other optical material, the first waveguide being optically coupled to the second waveguide such that an optical mode is transferred from the first waveguide to the second waveguide;
- wherein the slab is tapered proximate to the second waveguide to precondition the optical mode to negotiate the bend in the other optical material of the second waveguide.
