An optical system comprises a hybrid optical motherboard (M1) having a plurality of optical interconnections formed therein, and a connector (P1). A connector region (S1) is formed in, but does no t extend completely along, an edge portion of the hybrid optical motherboard (M1). The connector region (S1) contains a number of optical interconnections, and the connector (P1) contains an optical device (7). The connector (P1) is connectible to the co nnector region (S1) to align the optical device (7) of the connector with the optical interconnections contained in the connector regio n. The connector (P1) and the connector region (S1) each comprises first and second substrates (1, 2 and 11, 12) made of crysta lline material and containing intersecting planes which can be dilineated by etching. Each first substrate (1, 11) is formed with etched alignment groove means (3, 13), and each second substrate (2, 12) is formed with etched alignment groove means (4, 14) wh ich are complementary to the alignment groove means of the associated first substrate. The alignment groove means (3, 13 and 4 , 14) of the first and second substrates (1, 2 and 11, 12) of the connector (P1) and of the connector region (S1) are accurately al igned and contiguous when the two substrates are placed in face-to-face engagement, and the aligned contiguous alignment groove m eans of the connector can be accurately aligned, and be contiguous, with the aligned, contiguous alignment groove means of the connector region. The connector (P1) is provided with alignment means (5) for accurately positioning the associated opti cal device (7) between its two substrates (1, 12) with respect to the contiguous aligned groove means (3, 4) thereof.
