Claim Text:
1. A method of fabricating on a polymer a (single-mode) polymer waveguide (PWG) array and a stub so that the (single-mode) polymer waveguide (PWG) array and the stub are aligned with a silicon waveguide (SiWG) array fabricated on a silicon (Si) chip and a groove fabricated along a direction in which the SiWG is fabricated, whereby an adiabatic coupling is realized, the method comprising the steps of: preparing a polymer base layer; placing on the polymer base layer a cast having a groove corresponding to a core of the (single-mode) polymer waveguide (PWG) array and a groove corresponding to the stub; hardening the polymer base layer; and removing the cast from the hardened polymer base layer.
