Periodic thermal poling of fibers is a promising technique for efficient quasi-phase-matched second-harmonic generation. An initial value of 1 pm/V was reported by Myers et al. for the second-order nonlinearity in thermally poled silica. The main difficulty associated with thermal poling is the spreading out that appears when patterned electrodes are used to create the chi(2) grating structure. Recently, we discovered that poling in vacuo avoids the electrical breakdown in air that gives rise to this spreading out. In a previous paper we describe creating a chi(2) structure in a multimode fiber by poling in a vacuum evaporator using one periodic and one uniform electrode. The pitch of the mask was 20 µm, and a tilt between the fiber and the electrode pattern of about 45' was therefore necessary in order to achieve the pitch required (~28 µm) for quasi phase matching (QPM) at 830 nm. In the research described in this paper the same periodic poling technique was applied to a single-mode fiber.
