In this paper we study the feasibility of an infrared detector based on intersubband transitions in the conduction band of the junction between two semiconductor quantum wires. We show that by varying the radius of the wires it is possible to engineer a band structure of the junction that would be favorable for creating and detecting photocurrent. The suggested concept also allows for broadband detection based on arrays of wires with different radii.
