摘要： A spot-size converter (100) and a photonic device (1) comprising the spot-size converter (100). The spot-size converter (100) comprises a first end face (100a) and a second end face (100b) which are parallel to each other, and further comprises a substrate (101), and an isolation layer (102), a first waveguide (103) and a covering layer (104) which are located on a side of the substrate (101) and are sequentially arranged in a direction away from the substrate (101). The first waveguide (103) comprises a flat-plate layer (31) and a ridge layer (32). The flat-plate layer (31) comprises a first wide end (31a) extending to the first end face (100a) and a first narrow end (31b) extending to the second end face (100b) or having a distance from the second end face (100b), and the flat-plate layer (31) has a width decreasing in a gradient from the first wide end (31a) to the first narrow end (31b) and comprises a first equal-width portion (311) adjacent to the first narrow end (31b). The ridge layer (32) comprises a second wide end (32a) extending to the first end face (100a) and a second narrow end (32b) having a distance from the first narrow end (31b). The ridge layer (32) has a width decreasing in a gradient from the second wide end (32a) to the second narrow end (32b) and comprises a second equal-width portion (321) adjacent to the second narrow end (32b). The covering layer (104) extends to the second end face (100b) and extends to cover at least an end of the second equal-width portion away from the second end face (100b).

摘要： In one embodiment, an integrated circuit device includes a substrate, an electronic integrated circuit (EIC), a photonics integrated circuit (PIC) electrically coupled to the EIC, and a glass block at least partially in a cavity defined by the substrate and at an end of the substrate. The glass block defines an optical path with one or more optical elements to direct light between the PIC and a fiber array unit (FAU) when attached to the glass block.
