Abstract
An athermal package for fiber photonic devices includes at least two bonding regions at each end of the optical fiber containing the photonic device. At each end of the optical fiber, the bonding region nearest the photonic device (i.e., the inner bonding region) has a width that is less than that of the other bonding region (i.e., the outer bonding region). The smaller widths of the inner bonding regions allow for relatively precise control of the positions on the optical fiber that the inner bonding regions are attached. The larger widths of the outer bonding regions help provide reliable attachments.
