Abstract
A small-form-factor (SFF) blue-light optical pickup head (OPH) with holographic
optical element (HOE) has been fabricated and assembled. The assembly and alignment of
various components in the pickup head were facilitated by using a flip chip bonder.
Experimental results indicated that the focusing error signal (FES) of the assembled OPH
with the wavelength of 405 nm could be successfully detected. The linear range of the
FES was about than 4 μm. The gauge repeatability and reproducibility (GR&R) of
the assembly process was tested and found to be acceptable.
