“…Chalcogenide glasses (ChGs) have received a great deal of attention in recent decades with its excellent infrared and nonlinear optical properties [1][2][3][4][5] in the area of integrated photonics [6][7][8][9][10], supercontinuum sources [11][12][13][14], and alloptical switches [15][16][17]. Among them, many kinds of ChGsbased all optical switches are fabricated and experimentally studied, and the switching power as low as 105 MW cm −1 was obtained due to the large nonlinearity, which was approximately 200 times lower than that of silica [16].…”

Chalcogenide glass is an important nonlinear optical material that has attracted much attention in the areas of integrated photonics, supercontinuum sources, and all-optical switches in recent years. However, the current research mainly focuses on the nonlinear effect excited by light, and the research on its properties under the action of a DC field is still deficient. Here, a metal-cladding optical waveguide, which is composed of a chalcogenide glass film coated on a glass substrate, is presented to analyze the quadratic electro-optic (QEO) effect of the chalcogenide glass film. The DC Kerr coefficient and the whole components of the QEO tensor of the sample were experimentally determined by the free space coupling method.

Herein, the electrical switching behavior of both bulk and thin film forms of Se86–x Te14Bi x (0 ≤ x ≤ 4) chalcogenide glasses was investigated. The melt–quench-derived glasses were found to be amorphous, and the switching behavior exhibited a threshold-type response below a certain current limit (I th) for bismuth (Bi)-doped bulk samples. Interestingly, as current levels surpassed this threshold, a noteworthy change occurred in the switching behavior, converting it into a memory-type response. The threshold voltage (V th) exhibited a decreasing trend from ∼228 V to ∼36 V with an increasing Bi content, and differential scanning calorimetry (DSC) was utilized to study the phase transition phenomena and thermal stability of the amorphous glasses. These DSC results unequivocally confirmed that the transition from amorphous to crystalline phase occurred readily and at lower temperatures in the Se82Te14Bi4 composition. Furthermore, annealing studies were carried out to gain insight into the phase transformations that occur when the material makes the transition from an amorphous to a crystalline state. Subsequently, the same melt–quench-derived glasses were deposited as a thin film using physical vapor deposition (PVD) into a three-layered Al/Se–Te–Bi/Al device, and the memory switching voltage experienced a remarkable drop to 2.88 V compared to the bulk material. This exploration sheds light on the captivating electrical switching behavior of Se86–x Te14Bi x chalcogenide glasses and holds promise for potential applications spanning the realm of emerging electronics and phase change material (PCM) devices.
