Abstract
The present invention relates to an optical interconnection for interconnecting a first contact and a second contact, which need to be optically interconnected, the optical interconnection comprising: a nanorod formed on at least one of the first contact and the second contact; and a nanowire extending from the first contact or the nanorod formed on the first contact so as to transmit an optical signal toward the second contact or the nanorod formed on the second contact. The optical interconnection according to the present invention shows improved optical signal characteristics due to a reduction in coupling loss.

An optical interconnection for interconnecting a first contact and a second contact, which need to be optically interconnected, the optical interconnection comprising:
- a first nanorod formed on the first contact;
- a second nanorod formed on the second contact;
- and
- a nanowire extending from the first nanorod formed on the first contact so as to transmit an optical signal toward the second nanorod formed on the second contact,
- wherein each of the first and the second nanorods have a truncated cone shape such that the outer circumferential surface of each of the first and second nanorods becomes narrower as the respective nanorod extends away from the respective contact.
A method for making an optical interconnection three-dimensionally interconnecting a first contact and a second contact by a nanowire, the method comprising the steps of:
- a) filling a nanorod material solution into a micropipette;
- b) coaxially aligning a lengthwise axis of the micropipette with an axis perpendicular to a surface of the contact;
- c) forming a meniscus of the nanorod material solution in the coaxially aligned state;
- d) making a nanorod by evaporating a solvent from the nanorod material solution while lifting the micropipette in a direction perpendicular to the surface of the first contact;
- e) filling a nanowire material solution into a micropipette;
- f) coaxially aligning a lengthwise axis of the micropipette of step e) with an axis perpendicular to a surface of the first contact or a top surface of the nanorod disposed on the first contact;
- g) forming a meniscus of the nanowire material solution;
- h) making a nanowire by evaporating a solvent from the nanowire material solution while lifting the micropipette;
- and
- i) bringing the micropipette into contact with either the second contact spaced apart from the first contact or the top of the nanorod disposed on the second contact.
