Abstract
Using pure aqueous KOH solution and a one-level mask, the reflective micromirror in the direction <100> and the fibers self-aligned V-grooves in the direction <110> were fabricated on the (100) silicon. Reflective micromirror is a part of {100} family; the surface of the mirror is perpendicular at the optical axes. The deviation brought by manual assemble can be decreased by crystal orientation self-aligned between the micromirror and fibers. Using Atomic Force Microscope (AFM), the measured the surface roughness of the reflective micromirror is below 40nm, at a wavelength of 1550nm the reflectivity ofthe micromirror was measured to be higher than 80%.
