摘要:
An optical communication apparatus using a single optical fiber to effect a two-way communication at the same time. A light emitting element (132) emits its generated light through an optical system (133) to an optical fiber (76). A light having been transmitted through the optical fiber (76) is received by a light receiving element (136) via the optical system (133). The optical system (133) is set such that the value of the light amount M of stray light is given as follows: S - 2QN ≥ M > S / 2Q - N where Q is the value of the Q value representing a required communication quality, S is the light amount of a received signal from the other end of communication, and N is the total sum of Gaussian noise.

The present invention employs a spectral and spatial combiner (132) that is capable of maintaining equal optical path lengths of each spectral beam so that a single combined bean (148) can be produced and can be employed in a number of different applications such as a color camera device (Figure 28), a color recording device (Figure 23), a graphics presentation device (Figure 27), an electronic color filter device (Figure 30), a color projector device (Figure 25) and a multi channel optical communication device (Figures 31 and (33).
摘要:
A light receiving module (200) is provided, including a beam contraction module (201), a multi-core multi-mode waveguide (202), and a detector (203). The beam contraction module (201) is configured to receive a first optical signal, and contract a mode spot of the first optical signal, to obtain a second optical signal. The multi-core multi-mode waveguide (202) includes a cladding layer (2022) and N waveguides (2021). The multi-core multi-mode waveguide (202) is configured to: receive the second optical signal, and concentrate energy of the second optical signal in a plurality of waveguides (2021) of the N waveguides (2021), to obtain a plurality of third optical signals. The detector is an array formed by N sub-detectors. A plurality of sub-detectors of the N sub-detectors are in one-to-one correspondence with the plurality of third optical signals. The plurality of sub-detectors are configured to receive the plurality of third optical signals, to obtain a plurality of electrical signals based on the plurality of third optical signals. An area and an angle for receiving the second optical signal can be increased by using the multi-core multi-mode waveguide (202), to reduce impact of offsets of a center position and a pointing angle of a light spot on light receiving and detecting efficiency, and reduce a power jitter.
