Three dimensional polymer waveguide using hybrid lithography

Abstract: A three dimensional polymer waveguide with taper structure was demonstrated and fabricated by a reliable and effective hybrid lithography. The hybrid lithography consists of lithography to fabricate a polymer waveguide and gray scale lithography to fabricate a polymer taper structure. Laser ablation and shadow aluminum evaporation were designed for gray scale lithography. The length of the gray scale region ranging from 20 to 400 μm could be controlled by the laser power, the ablation speed, and the aluminum t… Show more

“…The micro-reservoir layer is made on PMMA cladding chip (the thermal softening temperature of the PMMA cladding chip is 105 • C) by using CO 2 laser engraver (the cutting speed of the CO 2 laser engraver is 100 mm/s, the power is 25 W). [22] The micro reservoir is a rectangular groove structure on the PMMA chip. There are two holes on the micro reservoir.…”
