摘要: An optical switching module has an waveguide substrate mounted on electronic circuit substrate. According to a first aspect of the invention, thin-film heaters, and trimmable thick-film resistors for adjusting current fed heaters. second also pair fiber pigtails butt-coupled The are secured ends supporter, which is attached heat sink fastened below third in depression invention reduces size module.
