摘要： A light receiving device includes a microlens 21 located in each of regions corresponding to pixels, the microlens being disposed on a rear surface of an InP substrate 1. The microlens is formed by using a resin material having a range of a transmittance of light in the wavelength region between 0.7 and 3 µm of 25% or less, the transmittance being 70% or more.

摘要： Bidirectional optical communication system transmits optical signals with two different wavelengths λ
1 and λ
2 (λ
1 2 ) between a broadcasting station and a plurality of ONU terminals. Bisecting separation of λ
1 and λ
2 requires expensive WDMs. λ
1 -selective photodiode which absorbs all the λ
1 light and allows all the λ
2 to pass through is proposed. The energy gap Eg
1 of the light receiving layer is determined to be smaller than hc/λ
2 and larger than hc/λ
1 . The λ
1 -selective photodiode and the other photodiode are positioned in series on a beam line, which dispenses with WDMs.

摘要： WDMs have been used to separate a plurality of signals spatially by the difference of wavelengths in prior bidirectional multiwavelength optical communication network. For excluding WDMS, linear PD/LD modules adopt eigen-wavelength photodiodes sensing only the light of an eigen wavelength but allowing all the wavelengths longer than the eigen wavelength. An n-member PD/LD module aligns (n-1) eigen wavelength photodiodes, PD1, PD2, PD3, ···, PDn-1 of λ 1, λ 2, λ 3, ···, λ n-1 and an LD of λ n which satisfy inequalities λ 1
